 Years have passed since Ted Striker heroically saved many lives by avoiding a plane crash. Working as a test pilot for a new Lunar Shuttle, he gets innocently sent into a mental ward after a crash of the badly constructed, computer-navigated spaceship. When he hears that the exactly same type of shuttle is scheduled for a moon flight soon, he breaks out to hinder the launch. Aboard, Ted finds his ex-ex Elaine Dickinson working as stewardess again and her fiancé Simon, a member of the committee that wants the Mayflower I to be launched. In flight, the ship s computer ROK 9000 takes control, killing the crew. Ted and Elaine manage to switch it off, and now it is up to Ted again to save the passengers  lives - if there only wouldn t be these flashbacks to the war and these people who know Ted and have no faith in his abilities at all.
