The Enterprise travels to the planet Janus 6 to assist the mining colony there. Kirk, Spock and McCoy beam down to the planet where Chief Engineer Vanderberg tells of a creature loose in the mine tunnels killing some of his men. The monster seems to appear out nowhere then disappears just as quickly. Finding that the creature, known as a Horta, lives in a newly opened part of the underground mining complex, Spock uses the Vulcan mind meld to determine why it is killing the miners. Written by

once remarked, in 1995, that of the Original Series, the only episode he could recall was this one, stating that "It impressed me because it presented the idea, unusual in science fiction then and now, that something weird, and even dangerous, need not be malevolent.
