Danny and Valerie Gray are forced to become ""parents"" to a sack of flour for a one-week school assignment. At the same time Skulker, ghost hunter extraordinaire, decides to pit Valerie and Danny Phantom against each other in a contest - with the winner earning the privilege of becoming his prey. When Skulker's orchestrated contest ends in a tie, he handcuffs Danny and Valerie and hunts them both through the Ghost Zone.
