Edward "Eddie" Spinola is a copywriter at a small publishing house in New York City. He starts using MDT-48, an experimental drug granting heightened intellectual, creative, and learning powers, and enabling its user to see meaningful patterns in large amounts of disparate data. Using his newly acquired intellect, Edward amasses a small fortune short selling technology stocks. His trading escapades don't go unnoticed, and he is offered a job by billionaire tycoon Carl Van Loon, mediating the merger between entertainment giant MCL Parnasis and Abraxis, the country's second largest Internet service provider – a deal he sees to completion.
However, his indiscriminate use of the drug leads to panic attacks and blackouts. Edward is suspected of bludgeoning Donatella Alvarez, the wife of a prominent Mexican artist, to death during an MDT induced fugue state. He further learns the full scope of the side-effects from his ex-wife Melissa, who had dabbled in the substance and suffered permanent neurocognitive damage, prompting him to gradually discontinue use of the drug.
Edward initially reduces his intake to half a pill a day, but this quickly proves insufficient to maintain the level of mental acumen required to work out the details of the merger, and he is forced to increase the dosage. Realizing he is on a treadmill of addiction, Edward tracks down another user, from whom he learns of the existence of a drug, readily available over the counter, capable of negating some of the harmful side-effects. Armed with this knowledge, Edward resumes taking MDT and is filled with a renewed surge of energy and motivation.
This proves to be a mere stop-gap measure, as Edward realizes the need to secure a steady supply. His stash running out, Edward makes a desperate attempt to blackmail the pharmaceutical conglomerate responsible for developing MDT into providing him with continued access to the drug. His gambit fails when men break into his apartment and steal his remaining MDT. He then receives an anonymous phone call on his land-line informing him that he had been under surveillance all along, and an unwitting guinea pig in a clandestine clinical drug trial.
Facing imminent death from withdrawal, Edward comes to terms with his own actions and travels to Mahopac, New York, where he seeks redemption by leaving a bag full of cash at his ex-wife's doorstep. He then continues driving aimlessly up north, and eventually checks into a remote motel along the Vermont highway, where he pens his account of the last few months of his life and the events leading to his ultimate downfall. As he drifts into a semi-conscious state, Edward watches on as the President – visibly under the influence of MDT – announces the deployment of US troops into Mexico in a televised address to the nation.
Limitless is a 2011 American thriller based on The Dark Fields. The film was directed by Neil Burger and starred Bradley Cooper, Abbie Cornish, Andrew Howard and Robert De Niro. It was released in the United States and Canada on March 18, 2011.
The screenplay roughly mirrors the events portrayed in the book, albeit with a number of significant differences. For example, the novel is set during the peak and subsequent collapse of the Dot-com bubble, with allusions by several characters to ”irrational exuberance” in the financial markets. Meanwhile, and while Edward mentions adverse market conditions indicating a bear market, the viewer is never given a clear time frame for the events portrayed in the film. Similarly, any mention of the growing tensions between the United States and Mexico is also absent from the movie adaptation, as is any reference to government involvement with MDT-48 (renamed NZT-48).
The role of several characters was also changed in the movie adaptation, while others are all together absent. Hank Atwood, for instance, who is shown to be quite fond of Edward in the novel, has no qualms about hiring a hitman to eliminate him and steal his supply of NZT in the film. Carl Van Loon, too, takes a similarly antagonistic view towards Edward, whom he tries to blackmail into doing his political bidding in exchange for a steady supply of the drug. Van Loon's daughter, the object of Edward's infatuation in the novel, is replaced by Lindy – who leaves him at the beginning of the movie, only to rekindle their relationship after being charmed by Edward's NZT persona.
(Illuminating) The Dark Fields is mentioned in the film as the name of the book written by the main character.
