The 1946 film ("My Darling Clementine") is a western which takes its inspiration from the life of Wyatt Earp (Henry Fonda), the frontier lawman, who teamed with Doc Holiday (Victor Mature) for the famous gunfight at the O.K. Corral.

When we get about 9 minutes into the film, Wyatt and his brothers Morgan and Virgil arrive at the 1882 lawless boom town of Tombstone, Arizona. They are seeking a night of relaxation, leaving their youngest brother James behind to tend their cattle herd. But, Wyatt will find that old man Clanton is right. He had said to Wyatt that Tombstone is a "wide-open town". It is a raw, rough, lawless and chaotic, sinful hellhole, filled with bustling, raucous saloons.

The Earps go to the Bon Ton Tonsorial Parlor; it is a barber shop according to Wyatt. During his shave, it is interrupted by gunshots that narrowly miss him and shatter the mirror in the shop. Wyatt becomes upset and wants answers. He sees that dance hall girls are running and screaming from the Oriental Saloon. A reckless, drunken Indian Charlie (Charles Stevens) has shot his gun into the air.
