EOS is an episode of Thomas' Adventures of Thunderbirds Are Go ( 2015 TV Series).
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, and the engines. Running out of air, John finds a way to reach Lady Penelope, who warns his brothers and the engines. Percy, Alan and Thunderbird 3 are soon sent to rescue John, with instructions to destroy Thunderbird 5 if the A.I. cannot be stopped.
