When Dr. Blight develops a new rocket fuel to assist in NASA'S planned mission to Venus, she comes under the watchful eye of the Planeteers, who know the fuel will only hasten the degeneration of the O-Zone layer. But Blight is able to maintain her cover when the President of the United States himself arrives to oversee production of the fuel. Due to security, the Planeteers cannot get near the President without causing concern, so they cause a distraction to get Ma-Ti and Kwame inside the compound. As they warn the President, Blight and MAL become wise to the Planeteers' presence and launches the shuttle prematurely, with Kwame, Ma-Ti, and the President inside. They summon Captain Planet, whose powers are later drained by the craft's fuel. When he tries to return their powers, Kwame's and Ma-ti's powers are rejected by the dense outer space atmosphere. Now, Cap must use his wits to find a way to stop Blight, while Kwame and Ma-Ti try to save themselves and the President from crash landing onto Venus.
