Zhero. the secret of water

Venice. On a full-moon night, the members of a secret society gather in an ancient palace. Bepi Galvano, luminary of physics, is about to celebrate his eightieth birthday just a few streets away. His neighbours, three brilliant kids, are throwing a big party in his honour. That very night, however, the professor goes missing in circumstances which have yet to be clarified. Perhaps, that mysterious league, the Lunar Society, is the key for the enigma of his disappearance... In a maze-like Venice, three young kids are about to launch into a race against the time. The future of humanity could be hidden in the professor's latest invention, an incredible machine capable of producing green energy from water. It's up to Bepi's kids, now, to follow in his footsteps, and prevent eternal darkness from descending on the world we know.
