One lazy summer afternoon, Tom and his three 12-year-old school buddies find a weird board game. They don’t know that every time they roll the dice on the board game, they open up a gate between the present and the past, and enter another dimension where they are dinosaurs! A belt around their heavy dinosaur necks contains a vial in which floats a piece of rock, Rockfroz. They’ll soon discover that this Rockfroz is the link between Earth and the world of the dinosaurs. Every time the kids are on Earth minding their own business, something can happen with the board game warning them to jump into action to save the dinosaurs from the evil clutches of Neceron.
