Every child wants to win a tour of the Challis Toy Factory. That is, until the lucky five go missing, the factory shuts down, and Challis goes into hiding.

Ten years later Justin Wilder -loser, punk, Challis Toy fanatic-plans on giving his friends one final adventure before they move on to college without him. This will be a night they'll never forget. The whimsical dreamland they expected turns out to be a beaten-up, rundown nightmare, and there's still a lot of magic left in the old toy factory, but it's darker than anyone could have dreamed of.

Will Justin and his friends be able to fight their way through a world of bizarre machines, deadly rooms, and monstrous toys, or will they become the newest permanent residents of a world where toys play deadly games with people?
