Ashley Judd's character is a waitress at a lesbian bar with a convict for a husband and a child who had been kidnapped 9 years prior. She meets a man named Peter who gets close to her, and they sleep together. That night, he feels a bug bite him. The bug is so small that at first Judd can't see it, but he convinces her that it's there. Very soon, they both believe the apartment is swarming with bugs, and they start exhibiting open sores on their body. Soon after that, the entire apartment is covered in tin foil and both of them have gone completely batshit. A doctor comes in and convinces Judd to give up Peter. Peter then comes out and stabs the doctor, claiming he's a robot. The insanity escalates and the film ends with Judd and Peter burning themselves alive. The entire time, it's quite clear that Peter is a paranoid schizophrenic and Judd is so desperate for human contact that she buys into his paranoia hook, line, and sinker.
