Quentin Davies, a boyish lawyer, is considered by some of his fellow citizens in Tombstone to be a lovable pain in the neck. Others find him simply a pain in the neck. He defends Mexicans and Indians, and his detractors fear he will put foolish ideas about rights in the heads of these nuisances. One day he intervenes in a sexual assault on the Mexican woman who runs the bath house behind the barbershop and the randy customer, a gunslinger from Yuma, vows to kill him. The Deputy Marshal on duty that day, Wyatt Earp, will not arrest the gunslinger but shows the lawyer how, if he has a mind to, to defend himself.
