Lawman

Lawman is a movie starring Burt Lancaster, Robert Ryan, and Lee J. Cobb. A lawman from Bannock arrives in Sabbath to arrest all the cattlemen whose wild celebration the year before resulted in the accidental death of an old man.
While passing through the town of Bannock, a bunch of drunken cattlemen go overboard with their celebrating and accidentally kill an old man with a stray shot. They return home to Sabbath unaware of his death. Bannock lawman Jered Maddox later arrives there to arrest everyone involved on a charge of murder. Sabbath is run by land baron Vince Bronson, a benevolent despot, who, upon hearing of the death, offers restitution for the incident.
