The children give their new friends a lift in their wagon, but as they learn of their destination, they warn them that there is a curse on the lake, at the bottom of which is an old submerged town. The party finally arrives at Calculus villa where he demonstrates his invention a camera which can project holographic images. It is part of a far more ambitious project a machine which will make actual copies of physical objects. Later, over dinner, Thompson and Thomson explain that they are Calculus bodyguards as they suspect that a criminal organization specializing in making art forgeries wants to steal his machine. Eventually, everybody goes to bed. In the middle of the night, Snowy wakes up Tintin at one point after hearing a noise outside, but Tintin shakes it off as bird calls. In fact, the noise is made by Calculus housekeeper, Madame Black, who is in league with Mr. Big as well.Next morning, while Tintin explores the local country with Niko and Nouchka unaware that there are cameras spying on his every move, and the Captain and the detectives play a game of golf, Snowy runs into a man in scuba gear who has obtained from Madame Black some plans stolen from Calculus laboratory. The man escapes by jumping into the lake, but Snowy manages to bite off a part of one of his flippers. After the Captain and the detectives tell Tintin what has happened, he gives the dogs the bittenoff flipper to sniff. While Gustav leads Haddock to a pile of abandoned tires, Tintin follows Snowy to a buried chain which, when pulled, opens a passage to a hidden cave where the criminals have stashed the stolen art. After getting sealed inside the cave, Tintin finds an underwater tunnel leading out to the lake. On his way through, Tintin gets trapped by a wire net, but Snowy who remained outside the cave dives in and chews through the net, saving Tintin from drowning. ........
