Tin Tin and Brains meet up with an archeologist they have just met, to investigate the ancient temple at the bottom of Lake Anasta. While seemingly safe, they are in fact under observation by their old foe, the Hood. Using the unspeakable power of his glowing yellow eyes, the Hood attempts to torture the location of the temple's treasure out of Brains, but he's unable to do so before International Rescue turn up to save the day.
However, determined to prove his theories correct and make amends for causing trouble, Brains sneaks out in the night and swims back to the temple, where he is again accosted by the Hood and left to die. Thunderbird 4 manages to rescue Brains before his air supply runs out and while the Hood escapes, he's forced to do so without his treasure.
Tropes:
- Adventure Archaeologist: Tintin and Brains are searching for treasure in an underwater temple.
- The Alleged Car: The taxi that takes the archaeologist to the adventure site, which is very ancient, and backfires a lot.
- All Myths Are True: It's very well hidden, but there really is a large cache of glittering treasure in the sunken temple.
- Are We There Yet?: The Hood mutters about his long journey through the desert to the lake.The Hood: Sand, sand, nothing but sand. How much further to this lake?
- Badass in Distress: The team of International Rescue members at the archaeology site are attacked by the Hood, and Brains is left buried to the neck in the desert sand as a form of torture.
- Cool Boat: We don't see much of the Hood's sub, but it is a sweet design and even manages to land a hit or two on Thunderbird 4.
- Glowing Eyes of Doom: The Hood uses these to hypnotise Brains, Tintin, and the professor.
- Hot Sub-on-Sub Action: after a brief battle, Thunderbird 4 hits and sinks The Hood's submarine.
- It's Quiet… Too Quiet: Lampshaded by Scott, as he overflies the danger zone, and at first, nothing seems out of place.
- Made of Iron: Thunderbird 4. Taken completely by surprise she takes a direct torpedo hit from the Hoods own Submarine ... which doesn't seem to do anything more than slightly scratch the paint.
- Obviously Evil: The disguise The Hood uses in this episode (a man in full Arab costume) doesn't exactly make him seem trustworthy. Later in the episode (when underwater), he encounters Brains again and doesn't even bother with the disguise.
- Pun:The Hood: Ah, my friends are just in time. In fact... dead on time!
- Sand Necktie: The Hood does this to Brains. Partly subverted however since he does not do it with the intention of slowly killing Brains, but to torture Brains into revealing information about a treasure he, Tintin and a professor were looking for.
- The Tag: Tintin and Brains visit the professor in hospital, but then hurry off rather suddenly, to return to International Rescue, without the professor knowing who they are.
- Too Dumb to Live: Brains going out on his own to make up for his earlier failure, while The Hood is still out there and the rest of the IR team around who would be willing to help? Some genius, that guy. He does at least take the precaution of keeping radio contact with Tintin.
- Underwater Ruins: The temple on the bottom of the lake.
