For most of this experimental, allegorical French movie, the story is told using a reversed color (negative) developing process for the film itself. The director of the film, Martial Raysse, is a painter and sculptor; this is his first full-length feature. The non-narrative story follows the adventures of a man in a cat-mask. He is seen, variously, rescuing people or raping women, or tenderly reassuring a young girl. In short, he is an unpredictable element. He joins forces with someone (Sterling Hayden) who is taking a raft around the world, or maybe out of the world. Highlights of the film are the short scenes which appear with their color the right way 'round.
