Stardate: 4385.3 --The Enterprise comes across a space probe as they go to establish contact with the reclusive Melkotians. The probe warns the Enterprise to immediately leave Melkot space. 

Kirk tries to contact the Melkotians, but there is no response and they continue with their orders. When they reach Melkot, Kirk takes down a landing party and they face death penalties for not heeding the Melkotian's earlier warning. The telepathic Melkotians draw on Kirk's memories for the manner of their execution... and come up with the Showdown at the O.K. Corral.

Goof--When the bartender asks Kirk and his men whether they want the usual to drink, Sylvia is standing behind Chekov with her hands at her side. In the very next cut, she has her hands on his shoulders massaging him.

Trivia--A scene that was never filmed included McCoy/McLowery (DeForest Kelley) offering to share his medical expertise with Doc Holliday (Sam Gilman) to treat his progressing tuberculosis.

Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
