Purgatory

An outlaw band led by Blackjack Britton and Cavin Guthrie rob a bank. During the subsequent gunfight, a woman named Dolly Sloan is shot and dies in the arms of Cavin's nephew Sonny. The gang flees and is pursued by a posse comitatus (common law). After passing through a dust storm, they escape through a tunnel and emerge at the other end in the town of Refuge. The gang is welcomed there but they are puzzled by the town's residents, who don't carry guns or swear, and who immediately flock to the church whenever the bell rings.
