While on patrol in deep space, Captain Kirk (William Shatner) and his crew find and revive a genetically-engineered world conqueror (Ricardo Montalban) and his compatriots from Earth's Twentieth Century.

And, a deleted scene from the episode.

Khan Noonien Singh (Ricardo Montalban) takes control of the U.S.S. Enterprise with his Genetically-Modified DNA ('Seed') Eugenics Super-Humans. Khan has placed Captain Kirk in the Compression Chamber, and the executive staff is in the Executive Briefing Room, where, held captive is Mr. Spock (Leonard Nimoy), Dr. McCoy (Deforest Kelley), Commander Montgomery Scott (James Doohan), Lt. Nyota Uhura (Nichelle Nichols), and traitor, Lt. Marla McGivers (Madlyn Rhue).

As phasers are being pointed at all of them, Dr. McCoy says that he doesn't normally say this to patients, but Khan owes him something, because, Dr. McCoy saved his life. Khan has Dr. McCoy stunned by phaser fire, and then, he tells Spock that McCoy is only stunned. Khan says that he's sure that Mr. Spock approves. Spock says that he only approves of the logic, with which he used, to take control of their vessel. Brilliant.
