Satan's Cradle was the fourth of producer Phil Krasne's "Cisco Kid" programmers for United Artists. This time, Cisco takes on a frontier megalomaniac, shyster lawyer Steve Gentry, who has taken over a mining town. Gentry's confederate is dancehall girl Lil who is as deadly as she is beautiful. When itinerant preacher Henry Lane is beaten to a pulp by Gentry's goons, Cisco and Pancho move in for the kill.
