Gambling, drinking, and living on the edge, ever beset by disease, Doc nevertheless maintains an inbred code of honor to violent necessity. He meets and befriends Wyatt Earp, following him from Dodge City in its wide-open, cow town heyday to a date with destiny in Tombstone. Ever trailing in Doc's wake, Kate is never far behind, her love drawn to the self-destruction of a condemned man, like a moth to the flame of inevitable demise.
Doc walks away from the legendary O.K. Corral gunfight. He survives the Earp vendetta ride. He escapes legal consequences of the killings in Tombstone. But he can never outrun the rider mounted on a pale horse. Dancing on the edge of oblivion, driven by fate and an unyielding will to live on his own terms, Lunger is Doc Holliday's story as he himself might have told it.
