hen the Enterprise trespasses into uncharted territory, Kirk, Spock, McCoy, Scott and Chekov are transported to a location that has all the trappings of the American Old West. It's October 26, 1881, and Kirk soon realizes they are in Tombstone, Arizona, on the day of the famed gunfight at the OK Corral between the Clanton gang and the Earps - with Kirk and company representing the ill-fated Clantons. If history is to be repeated, they will fairly all be killed so must use whatever resources availed to them to defeat the threat and survive. The solution, however - and the only way of escape - lies within them.
