 Government agent Jim Wilson (Bob Steele) arranges to be put in prison in order to gain information from an inmate about the robbery money, that has never been recovered, in a stagecoach holdup. In an arranged prison break by the Warden (Lloyd Ingraham), Jim escapes and, posing as an outlaw named Spike Manning, heads for the robbery location and joins a gang. Working with undercover agent June O Day (Nancy DeShon), they discover that Wells Fargo Agent Blake (Charles King) is the real ringleader behind the gang and are making progress until Muggs (Dick Cramer), a gang member who knows where the loot is hidden and also knows the real Spike Manning, shows up.
