Synopsis by Judd Blaise
In this episode of the famed science fiction television series, thanks to the interference of a powerful alien species, the crew of the starship Enterprise is forced to test their mettle as Old West-style gunfighters. In response to the Enterprise's unintentional destruction of one of their warning devices, the aliens choose to answer violence with violence and subject the Enterprise's command crew to a punishment drawn from their own minds. The image they choose is that of Tombstone, Arizona, and Kirk, McCoy, and the others find themselves cast as the Clanton Gang on the eve of the famed O.K. Corral conflict. The Enterprise officers must find a way to escape from their designated roles and free themselves from the illusion before they find themselves at the losing end of a gunfight.
