A mysterious meteor has just missed Earth, but a piece falls down into the polar sea. Two expeditions race to find it and the new element it is made of. Tintin, Haddock and some scientists make up one expedition. The second is purely commercial. After some hubbub Tintin gets ashore on an island (the former meteor). The new metal has fun, but unlikely properties, such as accelerating the growth of trees, mushrooms and spiders. Eventually the new island sinks into the sea. Tintin is rescued just in time, returning with a piece of the new metal.

Good clean fun. ( )
