Former lawman Rance Toller and his lover Angie Sutter foil a stagecoach robbery just outside the frontier settlement of Tombstone, Arizona, and in the process capture the notorious gunfighter Johnny Ringo. As a result, Rance is persuaded to accept the vacant position of town marshal, formerly held by one of the famous Earp brothers. Unfortunately, he soon falls foul of the Big Silver mining operators led by E.B. Gage, who want the law on their terms. With the dubious help of his new friend, Doc Holliday, Rance has to fight for his life against Gage's ruthless enforcers, as well as take on a band of murderous cattle rustlers and the vengeful Ringo, who has escaped a jail cell with mysterious ease. It is not long before brutal bloody violence explodes on the streets of Tombstone.
