During a joint operation between International Rescue and the Global Defence Force, a series of mishaps nearly ends in disaster. In the wake of the botched mission, Colonel Martin Janus takes over the GDF, imposing a strict set of restrictions on International Rescue. As Lady Penelope and Parker attempt to reason with the colonel, they begin to realise that he is not quite what he seems - then it becomes apparent that he really is an imposter working for the Hood.

An undercover operation involving Lady Penelope and a Parker to recover a stolen Repulser Magnetic Array for the Global Defence Force gets blown prematurely. Parker is taken prisoner by Banino using the power of the Repulser and he takes a stolen GDF flyer with Kayo, who was secretly acting as back-up, in pursuit in Thunderbird Shadow. The flyer crash lands on a factory roof and International Rescue intervene with Scott in Thunderbird 1 rescuing one of the factory workers and Lady Penelope saving Parker. Kayo confronts Banino to find he knows her secret; she lets him escape knowing she will have to reveal the truth of her past.
