A transporter malfunction splits Kirk into two separate versions of himself: a pansy and a constipated, angsty overractor.
See, usually it's the redshirt that's getting into trouble, but this time it's the redshirt who causes trouble. Fisher took a tumble down on Alfa 177 and got covered in a strange magnetic ore, so that when they beamed him up to sickbay he screwed up the inner workings of the transporter. Well, then they had to pack things up and leave before night came and it became 130 degrees below zero on the planet's surface. Kirk takes it upon himself to go up first... but the transport takes a little longer than normal.
After Kirk leaves the transporter room, Kirk enters the transporter room. Evil Kirk, that is. It's immediately apparent that this new Kirk is evil by the tone of the music, the angle of the camera and the guyliner. (Give 'em a break, it's the 60's). Evil Kirk runs amok around the ship before the transporter malfunction is discovered. He demands liquor from Bones, attempts to assault Yeoman Rand and generally goes around making angry faces.
By this time, Good Kirk has changed into his fatsuit so the two are now more easily distinguished. Also, Spock confronts him about the actions of Evil Kirk thinking it was him, and Good Kirk swears he didn't do anything. Eventually, after talking to Rand, they figure out there's an intruder on board. To make matters worse, Scotty figured out what was wrong with the transporter by beaming up a space dog.

Surrounded by men under blankets.
Back in sickbay, Good Kirk sits and ponders his decision while looking over his recovering evil half. Being the trusting, altruistic and naive guy that Good Kirk is, he lets Evil Kirk go... and Evil Kirk immediately tries to take over the ship. Unfortunately, Evil Kirk is not able to handle the strain of living without his good half, so he collapses and they bring Evil Kirk into the transporter room with Good Kirk who gives him a hug and they step onto the transporter pad. They beam him up and back in... And he's saved!
Immediately, Kirk commands Scotty to beam up the away team, and they survive with only minor frostbite. Nothing that can't be fixed.
This episode takes a classic sci-fi concept, that of exploring two halves of human nature by literally splitting a character in two, and makes it Star Trek's own classic story. Sure, there are things left to be desired, such as the William Shatner School of Acting, but the issues brought to light by the concept are more than enough to make up for it. Our "good" halves cannot survive, cannot function without our "evil" halves. They work in tandem to make a well-rounded human being. Beautiful episode, this one!
