Eleven year old Marcus loves video games and hates the beach. So he is not happy when his mum Holly drags him to Diamond Beach, the place she loved as a child.

Once there, Holly meets Coco, her friend from her childhood. She is there with her electronics-obsessed husband, Sterling Huckstepp, and their kids, cool teenage Newt, pizza-loving Edison and the family robot, Prot.

Opening a door into the basement of Holly's caravan, Edison discovers the most amazing amusement park. Whoever opens a door in the basement finds themselves in their very own dream vacation. But when the dream becomes impossible to escape from, it all begins to feel more like a nightmare: Marcus, Holly, and the Huckstepps find themselves trapped in a matrix of terrifyingly perfect dreamscapes peopled with strange characters that will allow them to do anything they want, except leave...

A whirlwind adventure at a breakneck speed.
