While beaming back aboard the Enterprise, a transporter malfunction results in two vastly different Captain Kirks being beamed aboard. His personality has in effect been split into two. One Captain Kirk is weak and indecisive, fearful of making any kind of decision; the other is a mean-spirited and violent man who likes to swill brandy and force himself on female crew members. Meanwhile, as Scotty struggles to repair the transporter, the landing party is stuck on the planet below with temperatures falling rapidly.

Kirk's alternate green wrap-around uniform was introduced so that the audience would be able to tell the difference between the good Kirk and the evil Kirk. See more
When "good" Kirk supports his double on the transporter pad, his left hand is lower than his right. It then cuts to a very brief shot of Spock and then back to the Kirks, and the left hand is now higher than the right. See more
Lt. Cmdr. Leonard 'Bones' McCoy, M.D.
Jim, you can't risk your life on a theory!
Being split in two halves is no theory with me, Doctor. I have a human half, you see, as well as an alien half, submerged, constantly at war with each other. Personal experience, Doctor. I survive it because my intelligence wins out over both, makes them live together.
Your intelligence would enable you to survive, as well.
