In 1881 Virgil Earp,marshal of Tombstone, suspects Billy Clanton and the McLaury brothers of stealing cattle and,backed up by his brothers Wyatt and Morgan and 'Doc' Holliday,challenges them to surrender near the OK corral. In the following thirty second shoot-out the suspected and unarmed thieves are shot in the back,leading to the Earps standing trial for murder - though they are exonerated by the judge,who also happens to be a relation. This retelling,along with commentaries,is a far darker version of the story in which the Earps are usually represented as the unequivocally good guys.
