God's Gun

When Sam Clayton's (Jack Palance) menacing rabble of outlaws descends upon Juno City, all semblance of law and order quickly disappears. As they shoot their way through town, brave priest Father John (Lee Van Cleef) attempts to discourage them and gets shot dead for his trouble. A young boy (Leif Garrett) relays what's happened to the priest's twin brother, a former bounty hunter named Lewis (also Van Cleef), who decides to come out of retirement and avenge the murder.
