Freshman high-school student Melinda has refused to speak ever since she called the cops on a popular summer party. With her old friends snubbing her for being a rat, and her parents too busy to notice her troubles, she folds into herself, trying to hide her secret: that star senior Andy raped her at the party. But Melinda does manage to find solace in her art class headed by Mr. Freeman.

Andrew and his older brother Carl enjoy listening to ghost stories that the local undertaker tells them. One night he tells the tale of a local farmer whose wife gave birth to Siamese twins, one being good natured while the other was clearly evil. The farmer, ashamed of them, kept the twins locked in their room. Eventually the twins got sick and died together, so the farmer sawed them in half and buried the good twin in a cemetery and the bad twin in a shallow grave near the house. Later, Carl and his friends decide to hold a séance in the cemetery where the good twin is buried, but they unintentionally awaken the bad twin instead. Gradually, he possesses nearly everyone in town and it is up to young Andrew to stop him.

A lonely nerd hires a dominatrix on his birthday, setting up a series of role-plays designed to convince her she is his mother reincarnate, and she deserves revenge.
