Harry, Callie, and Colton think they're trying out an ordinary new video game-until the screen pulls them inside.
Trapped in a mysterious digital world, each discovers an incredible power. But as they battle through impossible levels, they meet Finn, a mysterious boy who may know the secret to escaping.
Together, they must collect five hidden keys, outsmart a game that keeps changing the rules, and find a way home.
But escaping may take more than beating the game.
They may have to rewrite it.
