Captain Black mistakes a Mysteron camera for a cannon, which I understand since it looks like one, and attacks a Mysteron complex. The Mysterons misunderstand and start a war of nerves, putting Captain Black under their control. They threaten to kill the World President. Captain Scarlet and Brown are killed and reconstructed by the Mysterons. The first attempt fails, and during the second attempt Colonel White discovers that the Captain Brown that escorted the president wasn't really Captain Brown, and that Captain Scarlet is under the control of the Mysterons as well. This means the President is in danger. Written by movieguy3

An assured launch

You've gotta admit, it takes some nerve to kill off your hero in the first episode. As the series opener, this explains (as well as any of the episodes do) the origin of Earth's war of nerves with the Mysterons. I feel kinda bad for Captain Black. Brown at least had some dialogue before he turned bad and was killed off. But Black's there for a couple minutes, the martians are attached, and now he's their evil puppet (no pun intended). No characterization. And what made them choose him for the role and not the two other guys in the Mars rover? Such a heavy fate left unexplained.

Regardless, this is a first-rate series opener. It perfectly sets the show's trademark paranoid tone, and for a kids show, this is fairly serious stuff. But it doesn't skimp on the action, and the pacing is excellent.
