 Seven convicts are being transferred from the Mexico State Penitentiary to Yuma. They escape, but their leader, Dorf, garners a severe response from Lucas when he tries to grab Mark. The escapees rampage through North Fork and take a Sweeney, the bartender, hostage. A vindictive Dorf demands that Lucas surrender himself, or they will kill Sweeney. Sweeney s wife begs Lucas to help. Lucas must either agree to walk into the middle of the street unarmed, or risk Dorf carrying out his threat to murder Sweeney.
