The return of a vengeful ex-girlfriend sets into motion a series of gruesome events for a hapless Irish bachelor in director Robert Quinn's grim black comedy. Tommy (Andrew Scott) had thought he had seen the last of Jean (Katy Davis) after their recent breakup, but when she returns to stake her claim on Tommy's apartment, the confrontation that ensues makes their previous quarrels look petty by comparison. After leaving the apartment in the head of the fight to cool his head and gather his thoughts, he returns only to find that Jean has died and enlists the aid of his friend Noel (Darren Healy) in ditching the body and ensuring that no one ever finds out what happened.
At one point the main character puts his hands behind his girlfriend's neck in a strangling motion when she is annoying him. She doesn't notice. Later the characters get into a fight that turns physical. She rips up his cigarettes and smashes his CDs. She then pulls apart two of his trophies and throws pieces at him. He pushes her out of the way to leave the apartment. We later learn that when he pushed her she fell and hit her head on a table and died.
The main character's girlfriend doesn't like his pet bearded dragon. She does things like throwing a towel over it and throwing a piece of pizza crust at it.
