Plot
The film follows Jennifer, a photographer, and Batz. Jennifer has an over-evolved, hyperactive reproduction system. Because of her condition, she can only be satisfied by very intense sex, which occasionally results in the death of her partners.
Jennifer's co-worker offers to get access to a mansion for a special photo shoot. Meanwhile, at said mansion, Batz is trying to subdue his sentient penis, which is addicted to drugs. Batz sees one of the models during the shoot, and gets an erection. Jennifer witnesses this and becomes obsessed with him, convinced that he is the only man who can satisfy her. She steals his house keys and later breaks into his house. She sees him bring home a prostitute and begins to film it.
