In Tombstone, a new sheriff vows to clean up the town of outlaws like the O'Hara brothers and is assisted by a strange lawyer who always carries two large law books with him.

The town of Tombstone is at the mercy of the five dreaded O'Hara brothers: Ramon (Antonio Cantafora), Pedro (Enzo Pulcrano), Miguel (Calogero Caruana), Ryan (Antonio Danesi)& Slide (Mimmo Maggio). An expert gunslinger, Burt Collins (Fred Robsham), arrives in Tombstone and is immediately persuaded to take on the duties of sheriff. A mysterious lawyer, James Webb (Klaus Kinski), lurking mostly in the background and occasionally joins in on the action with his deadly law books.—John Tviland Bakken

Going under the name of James Webb, a mysterious, black-clad lawyer rides into Tombstone, a peaceful little town with three undertakers, packed with an assortment of books. But, the murderous O'Hara Brothers have taken over the entire territory, and with the town's sheriffs having suffered premature deaths, the swift and confident gunfighter, Burt Collins, turns up to represent the law. Perhaps now, Sheriff Collins can get a chance to clean up Tombstone and reclaim his stolen land; however, the powerful and merciless O'Haras are always one step ahead. What are the intentions of the inscrutable Webb? Above all, why is he always carrying two thick law books around with him?—Nick Riganas
