Best friends Lilli, Leo and Bea are having an exciting day at the beach. They have everything they need for fun, including their Questland game and their special amulets. During their sandcastle competition, they spot a message in a bottle. It shows strange hieroglyphs and one clear word: Help! At that moment, their amulets glow and, in a flash, they are back in Questland.

Transformed into the SuperQuesters - Lillicorn, Leo Zoom and Bea Bumble - they arrive on the banks of a dried up river in the desert. As they gaze at a towering pyramid, they meet Arid the Sand Sprite, who is very upset. Skitter the scarab beetle tells them that Arid's brother, Rainveil the River Sprite, has been captured by the sneaky archaeologist Professor Vortec along with his beetle friends. The professor plans to destroy the desert in pursuit of ancient treasure.

The SuperQuesters leap into action. Working with Arid and Skitter, they discover the professor intends to steal the cursed treasure using an ancient spell. Can the friends use their STEM skills and courage to crack secret codes, dive for treasure, navigate the dunes and defeat mummybots in a race against time to stop the professor?
