Captain Kirk gets duplicated in the transporter into a "good" Kirk, and a "bad" Kirk. There is a group of 4 men on the planet including Sulu who will freeze to death, but they cant be beamed up with the transporter causing doubles.
Great episode, with the evil Kirk always having the shadow on his face to make him look dark and bad. The doglike creature shown at the beginning of the episode is pretty funny looking, kind of like a unicorn dog or something. With a party down on the planet which will get incredibly cold as the day wears on, but the transporter making duplicates of good/evil in a person or animal they cant bring that party aboard. So Kirk tries to keep everything together but finds his will and power of command slowly weakening. This episode keeps you thinking and shows the difference between good and evil. All in all if you are a big Shatner fan, give the episode a go... he appears as two people .. how much more Shatner do you need? Anybody who liked the series ... watch this episode ... its a good one.
