《蛇与彩虹》是由比尔·普尔曼,凯西·泰森,扎克·默凯主演的一部恐怖片，Dennis Allan is an scientist who visits Haiti on the strength of a rumour of a drug which renders the recipient totally paralyzed but conscious. The drug's effects often fool doctors, who declare the victims dead. Could this be the origin of the "zombie" legend? Alan embarks on a surprising and often surreal investigation of the turbulent social chaos that is Haiti during the revolution which ousted hated dictator "Baby Doc" Duvalier. Often a pawn in a greater game, Alan must decide what is science, what is superstition, and what is the unknown in a anarchistic society where police corruption and witch-doctory are commonplace.
