Brains and Tin-Tin mount an expedition to find treasure in a temple on the bed of Lake Anasta in the Middle East, but the Hood learns of their plans through his psychic link with Kyrano.
A Trip to Lake Anasta[]
Virgil takes Brains and Tin-Tin to the Middle East, aboard Thunderbird 2 - where they meet up with Professor Blakely
Dive on The Lost Temple[]
Donning scuba gear, Brains and Tin-Tin dive into the lake - and take a first look at the lost temple. Brains removes a rock sample from the central column to take back for Professor Blakely to examine; but the Hood, observing from his 3E Submarine, believes that they've found the treasure already...
Visit From A Bedouin Tribesman[]
During the night the Hood, disguised as a Bedouin tribesman, knocks on the door of the expedition caravan...and when Brains opens the door, the Hood hypnotizes him.
The next morning, Brains regains consciousness to find himself buried up to his neck in desert sand. He calls for help, but Tin-Tin and Professor Blakely are still unconscious. The Hood appears, demanding to know where the treasure is, but Brains is unable to tell him.
Rescued In The Nick Of Time[]
Jeff Tracy, worried that Brains hasn't called in, dispatches Thunderbird 1 and 2 to the scene. Spotting Brains buried in the sand, Scott quickly lands; and he and Gordon soon dig him out.
A Nighttime Dive...[]
Scott reports that the Automatic Camera Detector in Thunderbird 1 has been activated, and Brains realizes that they've all walked into a trap.
That night, he undertakes another dive into the lake - this time, alone - and discovers treasure stored in one of the temple's pillars. But in so doing, he inadvertently trips over an alarm set by the Hood...and following a series of wires along the lake bed, soon runs into the Hood, who hypnotizes him once again.
Attempting to reveal more of the hidden treasure, the Hood blows up the temple - trapping Brains beneath one of the columns, as it collapses around him.
Rescued[]
With Brains trapped beneath a column, Scott brings down a Hydrostatic Hoist which he and Gordon are able to use to lift it clear. Gordon pulls Brains to safety - just as the cords on the hoist snaps and the column crashes back on to the lake bed.
A Hospital Visit[]
Brains and Tin-Tin visits Professor Blakely in hospital, where they find him already planning his next expedition. He'd like them to join him - but it turns out both would rather go on a nice, soothing rescue mission!
