Many years ago, a small, isolated tribe were cursed by spirits for their sins. One of the tribesmen crafts a clay piñata which the tribe put their evil into and then sends the object afloat in the ocean. Though the curse was lifted from the tribe, a great evil would erupt from the piñata should it be disturbed. Present day, a group of college students, consisting of Kyle (Nicholas Brendon), Tina (Jaime Pressly), Doug (Eugene Byrd), Jake (Nate Richert), Lisa (Lara Wickes), Carmen (Julia Mendoza), Larry (Aeryk Egan), Julie (Daphne Duplaix), Bob (Robert Tena) and Connie (Tressa DiFiglia), sail to a remote island for an annual Cinco de Mayo treasure hunt. There, every fraternity boy is handcuffed to a random sorority girl. Each couple is instructed to collect as many pairs of strewn underwear on the island as possible. The couple that collects the most underwear and presents them to Monica (Casey Fallo) and Paul (Garrett Wang), the judges, will receive $20,000. The groups consist of Jake and Julie, Doug and Carmen, Bob and Lisa, Larry and Connie, and Kyle and Tina. As the hunt starts, the pairs eagerly retrieve underwear, apart from Kyle and Tina who have just broken up with each other. Bob and Lisa find the piñata, accidentally bringing the object to life as it proceeds to beat Bob to death with a branch while Lisa runs away.
Kyle and Tina decide to forget about the break up and join in the game. Meanwhile, Lisa attempts to warn Larry and Connie of the piñata, but nethier of them believe her and continue on their search. As they do so, they pick up a shovel, and get a bunch of underwear from a secret stash. The pinata picks up the shovel, and crushes Connie's head before turning on Larry. Lisa goes to the camp, and tells Paul and Monica about what she saw. The judges, unsure about whether they should believe her or not, go to look for Bob. While they do so, Jake and Julie see the pinata, and Jake goes to open it. right before he smashes it, the pinata grabs him and rips out his testicles while it beats Julie to death. Paul is later killed and Kyle and Tina reconcile. A new group of Kyle, Tina, Doug, Carmen, and Lisa now leave when they see Bob ripped in half on a tree. Doug is hanged by the pinata. As Carmen and Lisa go back, Lisa takes a bathroom break right before Carmen gets her head chopped off. Monica finds Kyle and Tina. Lisa makes it to the camp and thinks Larry and Connie are in there just before she is killed by the pinata. Kyle, Tina, and Monica kill the pinata by blowing it up by a molotov cocktail.

- Originally, Demon Island contained no computer effects; the piñata monster was played by an actor in a rubber suit. After the final cut, computer effects were added to make the monster more frightening.
- This was Nicholas Brendon's second time to play a character who runs from and/or battles demons. His first time was on Buffy the Vampire Slayer, which he starred on from 1997 to 2003.
