A trio of thieves rob the Sherman Ranch and Relay station, wounding both Jess Harper and Mr. Frazer from the stage line office, who was carrying the money. With information from Jess, Slim Sherman, still sworn in as Mort Cory's deputy, is able to trail the thieves until they split up. Slim catches up with one, killing him in self defense, which puts Slim in danger when it turns out that the man he killed is Hank McGovern, son of Ellen McGovern, wealthy rancher in the area. Ellen refuses to believe her son guilty of theft and attempted murder especially since Slim cannot produce the money or a witness. With Slim's status as a deputy affording him some protection, Ellen McGovern puts a price on his head. Slim is in a race against time to prove Hank's guilt and find the money before Hank's two partners or he loses his own life. Slim's only allies are the reluctant Laurie McGovern, sister of the dead man and the equally reluctant Jim Lassel, Ellen's ranch foreman.
