Ordered to establish peaceful relations with the Melkotians and ignoring  a warning buoy guarding Melkot space, they go in anyway. The Melkotians demand punishment for Kirk and company on their bizarre planet. On Oct 26,1881, the crew is  made to reenact the gunfight at the OK corral. and assume the roles of the notorious Clanton gang who lost the shootout.

Melkot, Melkotians: true telepaths, no recorded contacts prior to this. Looks like a giant Lock Ness Monster, with glowing eyes. Able to effect a radical alteration in human thought patterns. Planet is unknown but is misty and mysterious. The set is sparsely recognizable as an old west town.

Gas granade invented to tranquilize the Erps, but it doesn't work.
