In Tombstone, Arizona, the sheriff is unwilling to stop Indian Charlie from shooting up the saloon owned by Ben Carter, so new arrival Wyatt Earp does. Earp is beaten by some of Carter's hired men for taking the law into his own hands.
Dance hall girl Jerry is upset with Earp, so when her sweetheart Doc Halliday gets to town, a showdown seems imminent. Earp and Doc instead become friends. Earp takes over as the town's lawman. Doc's former sweetheart Sarah Allen, arrives in town. Believing that he is no good for her, Doc estranges himself from Sarah, but Earp convinces that her relationship with Doc can be rekindled.
The two men work together after visiting entertainer Eddie Foy is kidnapped, and also when Jerry joins forces with Carter to plan the robbery of a gold shipment. Earp and Doc foil the robbery and escape with their lives. Later, Doc is forced to perform surgery to save a life, then is ambushed and fatally shot by Carter. Earp avenges his friend's death and Jerry, remorseful and distraught over her part in the robbery, picks up a gun and finishes off the last of the gang. Sarah chooses to stay in Tombstone to remain close to Doc, and Jerry leaves town.
The film was based on Stuart Lake's book Wyatt Earp: Frontier Marshal, published two years after Earp's death in 1929. Prior to his death, Earp and his wife Josephine ("Sadie") went to great lengths to keep Josephine's name out of the book, and she threatened litigation to prevent her name from being used in the film.[1]: 101 In 1934, she had successfully forced the producers to excise her husband's name from the first film. In 1939, she sued 20th Century Fox for $50,000 to prevent it from producing the remake of Frontier Marshal. After agreeing to remove Wyatt Earp's name from the title and settling with Josephine Earp for $5,000,[2] Fox released the film as Frontier Marshal.[3]
In Los Angeles, Josephine Earp befriended many celebrities, including Cecil B. DeMille and Gary Cooper. She received part of the money earned by sales of Lake's book about her husband as well as royalties from the film.[3]
