When town marshal Vic Falcone takes a bullet, he calls on the local preacher Tom McCabe to strap on a gun and wear the badge. The man who shot the marshal is in the town jail and awaiting trial, and the man's outlaw brother is out there somewhere, intending to free him. A lot for McCabe to handle, but even though he's a preacher, he's also the nephew of the gunfighter Johnny McCabe.
