Every man knew the name Wyatt Earp. Some called him the law. Others, that no badge should carry so much power. With his brothers beside him and the deadly Doc Holiday at his shoulder, Earp's word was law and few dared challenge it. Sent in secret to uncover the truth, investigator Dan Stockard soon discovers that in Tombstone, justice can be as dangerous as crime. With only the fiercely independent Nellie Cashman willing to stand beside him, he must navigate a town divided by fear, loyalty and suspicion. Tensions rise, hidden loyalties are tested and every trail leads towards a violent reckoning that will be forever be remembered as the most legendary gunfight in the history of the American West.
