A street-sweeping agency employee named Rob leads an unremarkable life by day but harbors a macabre fascination with death, harboring a collection of videotapes showcasing actual death and dismemberment. At home, he is in a strained relationship with his girlfriend Betty, who unrealistically dreams of a more romantic, idyllic life despite their small, run-down apartment littered with preserved animal remains and skewed symbols of affection. Their shared dark interest in the morbid and the forbidden serves as the glue to their relationship, but it is clear that this mutual obsession with death is a stand-in for their inability to connect on a more human and emotional level.

One day, a tragic car accident presents Rob with a gruesome opportunity: the retrieval of a decomposed corpse. Seeing potential in this grim discovery, he decides to bring the body home, an act that serves to escalate the couple's disturbing, intimate bond with the dead. Enthralled, Betty becomes increasingly invested in the macabre ménage à trois, which involves a variety of unorthodox and chilling rituals. As their bizarre infatuation with the corpse grows, it becomes apparent that their gruesome passion may have consequences. This fringe lifestyle and the pursuit of extreme experiences push the boundaries of their already strained relationship, leading them on a path that tests the limits of their disturbing fascination.
