Meanwhile, Steven heads out of town to look for Dodo with Ringo in town in search of Holliday. Steven and Kate are taken by Ringo to the Clanton ranch, where the Clantons recamp and tell their father, Pa Clanton, that they have killed an Earp. Wyatt Earp swears vengeance and starts to build a posse of lawmen to deal with the Clantons once and for all. Doc Holliday returns to Tombstone with Dodo, and offers his services to his old friend Earp too. Attempts by the Doctor to defuse the situation amount to little: there will be a gunfight at the O.K. Corral. On the one side are the three Clanton brothers and Johnny Ringo; on the other, the two Earps and Doc Holliday. At the end of the gunfight Ringo and the three Clantons are shot dead. Shortly thereafter the Doctor, Steven and Dodo slip away in the TARDIS.
