Trapped in the year 2473 in the Wonderscape, an epic in-reality adventure game, they must call on the help of some unlikely historical heroes, to find their way home before time runs out. But the Wonderscape is full of secrets and not everyone is who they seem. When the friends' arrival threatens to reveal a dark truth, they realise they must fight not only for their past, but for a future they might never see.
