Hell is being trapped with yourself.

Overview

An audiotape plays on small cassette recorder in a room. A female voice from the tape recounts her possible murder and fickle dalliances with a series of men, ruminating on which one may have killed her. At the other end of the room a woman, Sweetpea, tries desperately to escape. Is this Hell, the afterlife, or the inside of Sweetpea's troubled mind?
