Barton's family is massacred by outlaws. Vowing revenge, he sets out to hunt down the killers. Along the way he meets a mysterious, flute-playing gunslinger who claims to know the identity of the killers and agrees to help bring them to justice. But he has a secret of his own.

A gang of outlaws gather at a desert saloon after robbing a bank. However, the loot is missing and paranoia sets in, as the outlaws start knocking each other off

Reverend Miller arrives in Tucson where he wants to build a church. But on the very day of his arrival a gang carries out a raid on the bank and the people of Tucson, who are suspicious of the new reverend because he carries a gun, immediately blame him for the robbery. The sheriff saves him from lynching by putting him in jail. Then he asks the priest to find the gang and the booty; thus Miller becomes the Reverend Colt. His exceptional skill means that he can shoot hats off people's heads and their pistols from their pockets, but he never kills.
