After rescuing a falling air balloonist and his son from a violent storm, Virgil and Gordon are sent out to rescue an undersea research lab team from a series of earthquakes that have made the ground unstable beneath the lab. Using Thunderbird 2, Virgil grapples the lab (with the help of Scott in Thunderbird 1) to try and hold it steady while Gordon rescues the scientists from inside.
