Episode Description:
The childlike A.I. encountered in Japan suddenly takes control of Thunderbird 5, trapping John outside of it. The program, created by John as a game, believes it is defending itself from being shut down and is sending false monitor images to Tracy Island to deceive the others. Running out of air, John finds a way to reach Lady Penelope, who warns his brothers. Alan and Thunderbird 3 are soon sent to rescue John, with instructions to destroy Thunderbird 5 if the A.I. cannot be stopped.
