Thunderbirds Are Go! S01E10 - Tunnels Of Time

A few months after International Rescue uncover an ancient temple in South America, Lady Penelope, as a representative of World Heritage, visits it along with Parker, Gordon, and Professor Harold, an archaeologist of a dubious reputation whom Penelope suspects of stealing artifacts. On entering the temple, everyone becomes trapped inside except for Harold, who manages to escape but refuses to call for help, not wishing the temple to be destroyed. Suspecting something is wrong, Scott and Virgil head to the scene to provide assistance, as Gordon, Penelope, and Parker attempt to escape from the temple's many traps.
