Riding into town with a corpse in the back of his wagon, Sam Rickers (Don Keefer) claims to have killed fugitive outlaw Bob Hulbert, and demands the $1000 reward. When Matt (James Arness) examines the body, he notices two things: the dead man was shot in the back--and he doesn't look anything like Hulbert. Facing a murder charge, Sam insists that he shot in self defense, and his wife Letty (Catherine McLeod) backs him up. The plot thickens when a man named Caitlin (Robert Griffin) confronts Dillon, telling him that the picture on Hulbert's wanted poster is actually someone else. The fact that guest stars Don Keefer and Catherine McLeod were married in real life adds an extra dimension to the startling finale of this episode, which is based on the Gunsmoke radio broadcast of November 13, 1954. ~ Hal Erickson, Rovi
