The Enterprise finds a 20th century spaceship which contains dozens of people in suspended animation. While investigating, one of the people is revived automatically. His name is Khan, a strikingly handsome Sihk who charms the Enterprise's historian, Lt. McGivers. While recovering, Khan reads up on the nearly 300 years of history he's missed, plus a great deal of technical information on the Enterprise. Through research, Kirk discovers that he's a genetic superman that escaped after the Eugenics Wars of Earth's 20th century. But he's too late: Khan and McGivers have gone back to his ship, revived Khan's crew, and returned to commandeer the Enterprise. Before he's successful, the crew manages to lock out some controls of the ship. Khan attempts to coerce the bridge crew to give him the controls by torturing Kirk in a pressure chamber.

First mention of the Eugenics Wars, a vague backstory used as a "macguffin" in numerous Trek productions. See more »


At the hearing, when the witnesses get up to leave in the wide shot, two black marks (perhaps actor's positioning marks) are seen in the center of the floor. After a few close-ups, the next wide shot (as the first closing credit is shown) has no marks on the floor at all. See more »


Khan Noonien Singh: Captain, although your abilities intrigue me, you are quite honestly inferior. Mentally, physically. In fact, I am surprised how little improvement there has been in human evolution. Oh, there has been technical advancement, but, how little man himself has changed.
Khan Noonien Singh: Yes, it appears we will do well in your century, Captain.

What a way to set things up for the future.
12 May 2006 | by (Western Desert United States) – See all my reviews

This is another of my 3 favorite episodes of the original TV Series. Ricardo Montalban was incredible in this episode, and delivers one of the best performances of his life. Shatner and Nimoy are also excellent in this episode.

This is another one of those episodes that showed the TV audience that Kirk was more than just a Captain of a ship, and even more than just a regular Starship Commander.

Still, as we will find out in years to come, the "Space Seed" was truly planted, although it was probably not known at the time.

I give this excellent episode 10 out of 10, AWESOME!! Desert-Buddha
