A pretty but unstable young woman has a one-night stand with a man, but when she realizes that he doesn't want the long-term relationship that she does, she becomes unhinged and sets out to ruin his life.

A nymphomaniac goes to a sanitarium in hopes of being cured; it turns out the sanitarium is a front for a Satanic cult luring young women into a web of madness, torture, and sex... But mostly just sex.
