It was a normal, boring Wednesday. Another school day. Then the three friends discover something in the mud which changes everything as they are forced into an adventure which puts not only their lives at risk but the lives of their family as well. Propelled into a parallel America in the 1970's, they discover, in the worst way imaginable, that the technology they take for granted in their world is not so favourably viewed in this new world. But not everyone considers it a bad thing. One person wants it for themselves and is willing to do anything to get his hands on it. Under threat and alone in a world of strangers, will they be able to find anyone to help them return home?
