Nick and two other men who ride chocolate palominos (brown palominos with flaxen manes) are identified by a rancher as suspected lovers of his wife. He captures and locks the three men in his cellar, threatening to hang them unless one confesses. When Nick is fingered as the guilty party, he must escape with the rancher's wife to save both their lives. Hunted down by the rancher and his men, he must risk his life and the life of his horse for the woman, who may not be the victim she appeared. This episode marks the end of the on-screen career for Cocoa, Nick's faithful gelding, a chocolate palomino. He retires Cocoa at the end of the episode, and in later episodes he rides a large buckskin.
