Bonfire Night is Richard's favourite night of the year-a time for sparklers, pranks, and snatching all the best treats before his friends get a chance.
But this year, Richard has one prank too many in mind: stealing the Guy Fawkes dummy and hiding it in a decaying, abandoned building at the edge of the park.
Dragging his friends along, he sets up his trick, but the tables turn when they trap him inside and vanish into the night.
Alone in the darkness, Richard discovers an impossible stash of treats waiting for him.
But as he greedily digs in, the sweets take a twisted toll, and Richard finds himself stiffening, transforming, unable to move.
Then he sees a figure emerging from the shadows-himself.
As his double takes his place among his friends, Richard realizes with horror where he's really headed...
