The film begins when two friends, Jenny Tate and Becky Morton, are at a pier and decide to get their fortune told by Zela. She foretells that they will suffer a horrible fate, but they don't believe her and walk away laughing. A little while later, Becky realizes Jenny has disappeared and can't find her on the pier; Becky was driving. One night, while in a car together, Jimmy and his sister Ellie hit an animal and another car. They attempt to rescue the other driver, Becky Morton, but she is suddenly dragged and eaten by an unknown creature. Jimmy and Ellie are both slashed by the creature's claws. Jimmy starts to believe that the creature was a werewolf, but no one will believe him. He and his sister start to exhibit wolfish tendencies (such as both of them eating raw bacon, Ellie catching a fly in her bare hand, and being attracted to the smell of blood) but Ellie denies it, apparently proving her point by touching a silver picture frame and not getting burned. Jimmy becomes much stronger, as exampled when a bully named Bo forces him to join the wrestling team. He easily defeats three wrestlers, including Bo.Meanwhile, Jenny is torn apart in a parking garage by a wolf-like creature. Zela's prediction for Jenny and Becky comes true. Eventually, Ellie starts to believe the werewolf idea, and Jimmy proves it when he holds a silver cake server and gets burned (he then discovers that the picture frame Ellie touched was actually stainless steel). He goes to warn Ellie with the help of Bo, who shows up at their house to come out as gay and apparently likes Jimmy. Bo and Jimmy race to where Ellie is, and in the meantime she figures out that her boyfriend, Jake, is a werewolf. He confirms that, but claims it wasn't him that attacked her and Jimmy. Another werewolf attacks, seemingly proving his story. Bo and Jimmy try to help, but Bo is knocked out.The new werewolf is revealed to be Joanie, a publicist who had a one-night-stand with Jake and became a werewolf (with proof of a pentagram on her right hand). She wants revenge by killing all of the other girls he dates. He refuses to let her hurt Ellie, and she knocks him out. Joanie soon turns into a werewolf and starts attacking. Ellie and Jimmy fight her, and she finally runs and hides when the police arrive. The two draw her out by insulting her, which she (in werewolf form) gives them the finger. The police open fire, apparently killing her. The only way to kill a werewolf is to separate the brain from the heart. As she rises again, a cop shoots her in the head, finally killing her. Bo is okay, but Jake has disappeared.Jimmy and Ellie return to a wrecked home. Their dog bit Jimmy and became a werewolf as well and destroyed the house in an uncontrollable rage. As Jimmy goes to try to fix the power, Jake arrives. He reveals that he did in fact bite Ellie and Jimmy, and he wants Ellie to live forever by his side after he kills Jimmy. She refuses, and the two fight it out, but her werewolf side only emerges and disappears at small intervals, while he has complete control over his werewolf side and dominates the fight. Jimmy joins in, climbing across the ceiling and biting Jake, distracting him long enough for Ellie to stab him with the silver cake server, badly injuring him. Ellie decapitates Jake with a shovel and breaking the curse on her, Jimmy and their dog. A girl Jimmy likes named Brooke shows up with their dog, having learned where they live from Bo, who also shows up. Bo and Jimmy are now friends; Jimmy kisses Brooke and walks her home along with Bo. Ellie goes to clean up the mess that is their house
