Beamed up during an ion storm, which causes a transporter malfunction, the landing party of Kirk, McCoy, Scotty and Uhura find themselves in a mirror universe aboard a parallel Enterprise run by ruthless barbarians. The ion storm also caused their malicious counterparts to beam to the real starship. Kirk and the others must find a way home before they are discovered and exposed by their parallel crew members, who use treachery, back-stabbing and seduction to get what they want.
Did You Know?
In the late 1980s, the pop band Information Society
sampled Kirk's line, "It is useless to resist us," at the very beginning of their song "Walking Away", as well as "In every revolution, there's one man with a vision," on "Over the Sea". See more
When the landing party is in the middle of the cross-universe transfer, the USS/ISS Enterprise is seen in orbit going in opposite directions (USS Enterprise going counterclockwise [when viewed from above]; ISS Enterprise going clockwise). However, through the rest of this episode, the ISS Enterprise is going counterclockwise. See more
Captain James T. Kirk
What is this, Mr. Sulu?
Mr. Spock has orders to kill you, Captain. He will succeed... apparently. You will also appear to have killed him after a fierce battle. Regrettable, but it will leave me in command.
