The entire world is changed when Robert Xavier, a child prodigy, tries to bring his parents back from the dead. His mistake spawns a wormhole that coats the entire world in ice and snow.

Dylan and Kyle have just finished their annual snowball fight with the neighborhood kids. The two brothers instantly feel the effects of the new world, labeled "The Crysocape." Parents and buildings are no longer around. It seems as though only teenagers and children survived.

Once the survivors learn the key to return home, an item known as the perfect snowball, they form snowball teams to acquire the magical artifact. However, these teams quickly notice that not everyone wants to go home, back to normality. Some people want to rule this realm forever. Can these maniacal individuals be stopped? Will the perfect snowball ever be discovered or will madness take control and tear lifelong friends apart?
