Lucas thought Morley had died but it turns out he's a wanted man and wants Lucas to do him a favor: turn him in for the $500 reward money that's available. Morley desperately needs the money so his girlfriend, Beth Landis, can get treatment for a serious disease. Lucas thinks he's on the level and decides to go along. Unfortunately another cowpoke who once worked with them, Hamp Ferris, rides into town and is looking to collect the bounty on Morley himself.
