11 year old Sam Winchester is bored in the latest home the Winchester's are living in until he finds a secret door and discovers an alternate version of his life on the other side. At the surface, this parallel reality is eerily similar to his real life and the people in it, only much better. But when this seemingly perfect world turns dangerous, and his other family tries to trap him forever, Sam must count on his resourcefulness, determination and bravery to escape this increasingly perilous world and save his dad and brother.
