Plot[]
Every Halloween all monsters become humans for the night but a monster called Mark has asked an agent demon, Vikki Devyne, to make him human forever. Thanks to Vikki Devyne, all the now human monster children are unable to change back into monsters, and the parents turn to June to help. She has to make a deal to get a protein shake by wrestling a demon that goes by the name of "Jordan The Destroyer", managed by a promoter with a Don King-style hairdo, before midnight, or else the children will not turn back into monsters and remain human forever.
