Joey Harker is an average high school student living in Greenville. He had trouble finding his way around his own house, let alone the town. On a field trip set by his Social Studies teacher, Mr. Dimas, Joey found himself lost in the city. He then entered a strange fog and when he emerged, everything had changed. All the cars were brightly coloured and the police cars was flashing green and yellow instead of blue and red. He went back home and discovered that he does not exist anymore, instead a girl named Josephine lived there. He ran outside and met a man wearing a mirrored mask. The man introduced himself as Jay. Before Jay could explain anything, three men appeared, standing on floating silver disks and wearing grey outfits appeared, all trying to catch Joey using silver nets. Joey runs, unintentionally entering the fog again.
