God's Gun

One day Sam Clayton (Jack Palance) and his gang arrive in the small town of Juno City where Father John (Lee van Cleef) is the priest of the local church. The gang wreak havoc in town, raping a woman and knifing a man in the back. They leave town, only to be caught by the fearless but unarmed Father John. After that, the gang member responsible for the murder is broken out of jail. Vowing revenge, the gang ambushes and guns Father John down on the steps of his church, and then take over the town while waiting for the arrival of the next stagecoach. However, Johnny O'Hara (Leif Garrett), a local boy, manages to escape with a couple of their horses and rides off to Mexico in the hope of finding the priest's gunfighter twin brother (van Cleef). They meet and set off back across the border to clean up the town. Meanwhile Sam Clayton discovers that he is Johnny's father. Also, it is revealed that some fifteen years earlier, during the Civil War, Jenny O'Hara (Sybil Danning) had been one of Clayton's victims, adding to the mystery of Johnny's paternity.
