影片描述了罗马帝国史上最荒淫的暴君卡里古拉王荒淫无度，凶残暴虐的一生，他长期与妹妹保持着不伦之情，心理和精神上都极度不正常，所以他的所有行为都伴随着荒谬、疯狂和不可理喻。称此片为情色影片史上的史诗性巨作，绝对当之无愧。

Lise, a mentally unbalanced middle-aged woman, travels from her home in Hamburg, Germany to Rome, Italy where she embarks on a fatal destiny that she had helped to arrange for herself – a premeditated search for someone, anyone, with whom she could form a dangerous liaison. Lise meets a variety of people during her journey and stay in Rome who include Bill, a lecherous British businessman that she meets on the plane to Rome who tries to seduce her; Carlo, a young man whom Lise tries to know more about; an elderly Englishwoman named Mrs. Fiedke whom Lise bonds with to go shopping; and Pierre, a Frenchman who picks up Lise hoping to seduce her as well.
The film is told in a non-linear narrative as throughout the film are scenes of the local Rome police interviewing all the people that Lise interacted with as well as investigating the reasons for her strange behavior that led up to her own murder.
