Having cryogenically frozen himself to preserve his 1% Speed Force energy, Barry Allen awakens when Eva McCulloch is spotted destroying Black Hole's remnants. He tries to convince her to stop and release his wife, Iris West-Allen, from the Mirrorverse, but to no avail, as Eva ends her latest attack by destroying Sam Scudder, her first mirror duplicate, in front of Rosalind Dillon. Cecile Horton interrogates Dillon, learning that she is working with Eva. Using her empath abilities, Cecile gets Dillon to reveal that Eva plans to use a bomb to destroy a Black Hole plane over Central City. Meanwhile, Nash and the Wellses occupying his mind realize they can activate Barry's Artificial Speed Force (ASF) generator, but it would result in Nash's death. He attempts to explore other methods but, with time running out, Nash sacrifices himself and the other Wellses to restore Barry's speed. Barry saves Central City and intends to inform his friends about Nash's sacrifice. Elsewhere, Iris attempts to escape the Mirrorverse. Eva discovers she is also a mirror duplicate and the real Eva died in the S.T.A.R. Labs particle accelerator explosion.

After mourning Nash and the Wellses, Barry and Cisco Ramon work towards saving Iris, Kamilla Hwang, and CCPD Captain David Singh by opening a portal to the Mirrorverse. Barry discovers the ASF granted him speed-thinking, allowing him to predict outcomes while causing him to become impersonal. Using his new abilities, he exposes Eva as an imposter on live television, forcing her to flee. However, a choice emerges: save Iris or save Kamilla and Singh. When Barry prioritizes saving Iris exclusively, Cisco, Frost, and Allegra Garcia join forces to stop him, but fail. Meanwhile, Iris plans a rendezvous with Kamilla and Singh, but they experience seizures. When Barry opens the portal, he forces Iris to come through alone, but she also experiences seizures. This shocks Barry into realizing what he has done and disabling the ASF. Elsewhere, a maddened Eva schemes to take over the world by replacing everyone with mirror duplicates while a confused Earth-1 Harrison Wells materializes where his corpse was 20 years after his death.

Eva begins replacing people with mirror duplicates. Sue Dearbon and Ralph Dibny return with evidence to exonerate Sue of Eva's crimes, but Ralph has become a blob since the destruction of McCulloch Technologies. Though Eva convinces Barry he cannot win, Wells comes to S.T.A.R. Labs and reminds him that he is the Paragon of Love. As Barry checks on Iris, he revives her. Barry and his team re-activate the ASF and fight the duplicates while Barry revives the original Speed Force before he and Iris convince Eva to stand down. Showing remorse, Eva tries to stop her duplicates, but they become too powerful, so she joins forces with Barry and Iris to destroy them. After freeing her prisoners, Eva leaves for the Mirrorverse to start anew. Claiming that he can now perceive all of his life at once and travel freely through time and space, Wells decides to put himself in a time loop so he can live peacefully with his wife, Tess Morgan, while an exonerated Sue and a recuperating Ralph travel the world to stop other Black Hole-esque organizations. 18 hours earlier, when Barry and Iris revived the Speed Force, they unknowingly released four differently colored lightning bolts.

Meanwhile, Abra Kadabra returns and lets himself be arrested by A.R.G.U.S. so he can complete an anti-matter bomb that he intends to use on Central City, making Barry suffer in retaliation for his family being erased from existence following the Crisis.

Due to Eva using her Mirror Gun on Caitlin, Frost's metahuman DNA created a new body. Caitlin and Frost argue over whether to re-merge or stay separated, but eventually agree to the latter. Barry is visited by the Speed Force, as his mother Nora Allen, carrying the same energy signature as the monster that attacked Barry and Kadabra, nicknamed "Fuerza." Barry gives the Speed Force his speed gauge to monitor its health before fighting a new enemy, Psych, who is using fear waves to trap everyone in Central City in perpetual nightmares. Barry is injured by one involving Eobard Thawne and Savitar. Team Flash uses Barry's speed, Cecile's abilities, and Clifford DeVoe's hover-chair to produce a courage wave to stop Psych. However, he disappears and Barry returns to his cryogenic chamber to recover. Elsewhere, Kristen Kramer, a liaison from the Governor's Municipal Logistics Commission, arrives at the CCPD, where she tells Joe that she is there to arrest Frost. Later, the Speed Force says that she was attacked by Psych and Fuerza and both of them are "like her."

While setting one near Chester's hometown, however, they get trapped in a time loop of the day before Chester's dad, Quincy, died in a car crash. With Quincy's help, Chester and Cisco build a device to detect and protect themselves from the "time god" Deon Owens, a high school quarterback who is attempting to prevent an injury that ruined his football career. Chester convinces him to let go of his past and that the future remains unwritten, causing Deon to realize he can change everyone's futures before vanishing, thereby ending the time loop and returning Chester and Cisco to the present. The two fail to find Deon, though they believe he is unaware of the Speed Force's revival. Cisco later discovers three other "forces," names them Still, Strength, and Sage, and determines Deon, Fuerza, and Psych are their respective conduits. Meanwhile, Barry emerges from his cryo-chamber and Iris bonds with the Speed Force before inviting it to stay with her and Barry. Elsewhere, Chester begins working on his father's old project while Joe warns Frost about Kramer, though Frost refuses to hide.

Despite being asked not to, Frost visits her old bar to find information on the criminal from the new bartender, Mark Blaine. Now calling himself "Chillblaine," however, he reveals that he created the microchip before he was fired and used his own cryogenic technology to replicate Frost's powers and frame her. He defeats her, but she stabs him. Barry and Allegra arrive and provide medical attention while Frost reveals she recorded Blaine's confession. As Kramer and the police arrive, Frost chooses to turn herself in and surrenders peacefully.

"Nora" attacks Iris and uses Barry's powers to kill Alexa. Meanwhile, at Frost's trial, Kramer attempts to force her to take the metahuman cure instead of prison time. Distraught, Caitlin has her mother, Carla Tannhauser, test if the cure would harm Frost. Cisco helps Caitlin and Allegra break into CCPD to neutralize the cures. However, Kramer accuses Frost of the act and reveals another vial she procured from A.R.G.U.S. Tannhauser confirms the cure will not harm Frost and urges her to take it, but Frost is worried she will lose her identity.

Barry, Cisco, and Chester enhance the tachyon device to extract the Forces' particles before Barry retrieves Wells to create a "time bubble" to protect the timeline. Realizing Barry's intentions, however, Deon arrives and destroys the device. During Team Citizen's search, they are ambushed by Psych, who gives Iris nightmares of "Nora." Chester fixes the device while Joe tries to dissuade Barry from his plan, but Barry and Wells go back in time regardless. The extraction revives Alexa and erases Psych and Deon in the present.

Cecile advises Joe that Kramer must stop her hunt on her own, leading to Joe resigning from the CCPD to remain righteous. Concurrently, Barry, Cisco, and Caitlin train Alexa to control Fuerza, though Barry's determination to have Fuerza fight Psych results in Alexa injuring Cisco and becoming unmotivated.

However, Deon and "Nora" arrive and attack Iris, Alexa, and Psych.

Production

Development

On January 7, 2020, The CW renewed the series for a seventh season. At San Diego Comic-Con 2019, series star Grant Gustin implied it could be the final season as none of the actors were contracted for beyond seven seasons. However, the show was later renewed by The CW on February 3, 2021, confirming that it would continue with at least an eighth season.

Writing

The sixth season ended prematurely, with 19 episodes out of the scheduled 22 due to the COVID-19 pandemic. Showrunner Eric Wallace said the remaining three episodes, which had been written, would become the first three episodes of season seven. He conceded there may be a few small adjustments made based on how the pandemic would affect shooting, but said Eva McCulloch's story "is on a very specific trajectory that we want to honor and finish." Wallace continued that he thought having these three episodes start season seven was "making it stronger because it's forcing us to look at these two separate things – which is the end of Eva's story and the beginning of the next villain's story and how he relates to Barry and Iris —" and making a strong connection between them. While cast member Danielle Panabaker was initially written out of some episodes in the season to accommodate her maternity leave since she gave birth in April 2020, Wallace said there had been discussions about whether to write her back into them since the pandemic resulted in production delays, though he noted the rewriting process was "tricky". Like the sixth season, the seventh season would be divided into multiple "Graphic Novel" arcs, though Wallace said they were "not going to be broken up in the way I think folks expect." The "Graphic Novels" are known as the third and fourth graphic novels, continuing from season six. Wallace said all four would be connected as he was planning to tell "one big story" over season six and seven. "Reflections and Lies", the second "Graphic Novel" of season six, ends with the third episode of season seven.

Regarding the character of Ralph Dibny / Elongated Man, given actor Hartley Sawyer's firing from the show, Wallace said they would be giving the character "a rest for while. But we will leave the door open" for a version of the character to appear again. Given Dibny's powers allow him to alter his appearance, Wallace stated that it created "a couple of ways" for Dibny to "still appear in at least one episode this season to wrap that storyline up, that gets us what we need and still allows fans to say goodbye to the character, at least for the indefinite future." Wallace also revealed they had a planned storyline for Dibny with another character that would have tied into the season's main villain. As a result, another character was utilized for that storyline and Wallace said "the storyline became so much stronger" because it became more of an emotional journey for them, going "somewhere that we never imagined they would until many seasons down the line". Despite setting up the relationship between Dibny and Sue Dearbon, Dearbon would still appear in the season, assisting Team Flash "in an unexpected way". Wallace later said that Joe West's storyline in the season would be "inspired by societal changes happening in today's world".

Casting

Hartley Sawyer was fired by The CW after his past social media posts with racist and misogynistic references resurfaced in the wake of the George Floyd protests. The decision was met with both praise and backlash, with some accusing the CW of supporting cancel culture.

Main cast members Grant Gustin, Candice Patton, Danielle Panabaker, Carlos Valdes, Danielle Nicolet, Efrat Dor and Jesse L. Martin return as Barry Allen / The Flash, Iris West-Allen, Caitlin Snow / Frost, Cisco Ramon, Cecile Horton, Eva McCulloch, and Joe West. Tom Cavanagh, in addition to returning as Nash Wells, also plays Harry Wells, H. R. Wells, Sherloque Wells, Earth-1 Wells and Eobard Thawne / Reverse-Flash. Brandon McKnight, who plays Chester P. Runk, was promoted to the main cast on March 3, 2020, while Kayla Compton, who plays Allegra Garcia, was promoted to the main cast two days later, on March 5, 2020. Hartley Sawyer was expected to return as Ralph Dibny / Elongated Man in the season, but on June 8, 2020, he was fired from the series after his past social media posts with racist and misogynistic references resurfaced in the wake of the George Floyd protests. Sawyer's character eventually made his appearance in the third episode "Mother", portrayed by an uncredited actor. On December 1, 2020, David Ramsey was revealed to be reprising his Arrow role of John Diggle in the season. On January 13, 2021, Jon Cor was cast in a guest role as Mark Stevens / Chillblaine for the seventh season. On March 30, 2021, Jordan Fisher was cast in a recurring role as Bart Allen / Impulse. On May 4, 2021, it was announced that Cavanagh and Valdes would leave the series after the season concludes. It was originally planned for Cavanagh to leave after season six, but he remained to properly conclude his characters' storyline in the seventh season's first three episodes; he is credited as a special guest star for his later appearances. In the same month, it was revealed that Jessica Parker Kennedy and John Wesley Shipp would be reprising their roles as Nora West-Allen / XS and Jay Garrick.

Filming

The episode that would have been season six's 20th was 90% filmed before being announced as the season seven premiere. The season was scheduled to begin filming on October 1, 2020. However, by September 29, the start of filming was indefinitely delayed because of delays in receiving COVID-19 test results for the cast and crew. Filming eventually began on October 9. On November 29, filming was suspended following a member of the production testing positive for COVID-19, and resumed by mid-December at Cloverdale. Filming concluded on May 22, 2021.

In early August 2020, The CW released several posters of the Arrowverse superheroes wearing face masks, including the Flash, with all posters having the caption "Real Heroes Wear Masks". This marketing tactic was used to "raise public awareness on the efficacy of facial coverings preventing the spread of COVID-19." In early December 2020, the titles for the first five episodes of the season were revealed.

Release

Broadcast

The seventh season premiered on March 2, 2021, delayed from its previous date of February 23, 2021. Despite premiering much later than previous seasons, it was not expected to have a much shorter episode count. In September 2020, Wallace said the number of episodes for the season had not yet been decided, and that would depend on when the season would begin filming safely. On May 25, 2021, it was confirmed that the season 7 finale would be on July 20, and that the season would have only 18 episodes.
