 Comanche Creek, Colorado, 1875: Prisoner Jack Mason is broken out of jail by a gang of strangers. They use him in a robbery, then when the dead-or-alive reward is high enough, they shoot him and collect. The National Detective Agency, now knowing the gang s methods, arranges to have agent Bob Gifford jailed in Comanche Creek for train robbery. The gang takes the bait (not before Gifford catches the eye of lovely saloon-keeper Abbie). But how will the bait get off the hook?
