In a 1950s-era alternate universe where domesticated zombies play a functional role in society by delivering the milk, carrying the mail, and even helping out with household chores, one boy is about to find out just how big of a personal responsibility "pet" ownership truly is. When the Earth passed through a cloud of space dust and the dead arose from their graves to devour the flesh of the living, it first seemed that all hope for humanity was lost. Society's rapid slide into chaos, however, was soon halted when scientists at a company called ZomCom created a special collar that turned the rampaging animated corpses docile. Now, thanks to ZomCom, everything is under control -- or is it? Timmy Robinson (K'Sun Ray) isn't quite convinced. Quiet and withdrawn, the skeptical young boy spends so much time locked away in his room that he's almost become invisible around the household. His mother Helen (Carrie-Anne Moss) has recently purchased a zombie to help keep things tidy around the house though, and when the creature attempts to engage the curious youngster in a game of catch, a friendship is forged between boy and zombie that finds the amiable gut-muncher nicknamed Fido (Billy Connolly) practically becoming a part of the family. Things take a turn for the worse however, when Fido's collar malfunctions and Timmy's neighbors begin dying in droves. When ZomCom's top zombie control specialist Mr. Bottoms (Henry Czerny) moves in across the street from Timmy, the increasingly complicated situation threatens to place a serious stumbling block in the path of human-zombie relations.
