Up from the Depths Part 1[]
Deep in the Mariana Trench a survey team encounter the TV-21, a prototype Thunderbird vehicle that was flown by Jeff Tracy, when a systems failure causes the ship to be stranded on the seabed. International Rescue arrives to rescue the crew but the Mechanic suddenly takes control of the surveyor and uses it to crush Thunderbird 4. Gordon gets out just as his ship is destroyed and now must use the TV-21 to rescue the crew. Meanwhile, Lady Penelope and Parker are investigating into how the Hood is communicating with the Mechanic.
Up from the Depths Part 2[]
After the Mechanic's ship flees the scene with the TV-21 Scott chases after it but Thunderbird 1 is unable to grab the enemy ship and suffers damage. The Mechanic then steals a GDF vault containing iridium, with Ned Tedford inside, and sends his ship into space. With two Thunderbirds out of commission Thunderbird 3, with help from MAX, is modified with weapons so that Alan can fight the ship while Scott tries to recover the vault and the TV-21. Meanwhile, Kayo, Lady Penelope and Parker head for Scotland to search for the Mechanic.
