"Undercover" is the 25th episode of Thunderbirds Are Go!, and was broadcast on Saturday, January 16th, 2016.
At a hangar at an unknown airport, a black arms dealer called Banino meets with Parker and Lady Penelope who were impersonating a man called Mr Mendocia and his assistant. The operation is watched by Kayo, Colenol Casey and the GDF from their control centre and an aerial transporter above the hangar. Inside the hangar, Parker shows Banino a collection of gold lidium before the dealer shows him a Repulsor Magnet Array, a powerful supermagnet stolen from Houseman Industries. At the GDF control centre, Ned Tedford arrives with a plate of food but accidentally puts it on a button, causing the soldiers inside the GDF flyer to drop into the hangar. Banino uses the magnet to attack the troops and escapes with Parker, the repulsor and the lidum in the flyer.
Kayo pursues the flyer in Thunderbird Shadow but Banino uses the flyer’s missiles to ward her off. Despite Kayo’s objections, Scott who was watching the operation from Tracy Island heads to the scene in Thunderbird 1. On the flyer, Banino smashes the controls with the repulsor’s case before bailing out in a hang glider with Kayo in pursuit. In FAB 1, Lady Penelope contacts Parker to land the plane at a nearby factory but the weight of the plane causes the roof to collapse. While the workers evacuate, Penelope breaks into the plane to save Parker while Scott rescues the lone worker remaining in the factory.
Meanwhile, Kayo encounters Banino and demands the repulsor and the lidium but it turns out the repulsor was missing due to Parker snatching it while hugging Banino on the plane earlier. Banino shows a photo of her and the Hood before fleeing. Back at the Factory, Parker saves Penelope by using the repulsor to stop the plane from crashing on top of them before breaking out. Kayo tells Scott and the others about Baninos escape before saying she will tell her secrets to the rest of the Tracys back home.
