In an Earthly world resembling the 1950s, a cloud of space radiation has shrouded the planet, resulting in the dead becoming zombies that desire live human flesh. A company called Zomcon has been able to control the zombie population. Zombies can be temporarily neutralized by being shot, but can only be permanently neutralized by their brain being destroyed. Their ultimate disposal is through cremation, or burial, the latter which requires decapitation with the head being buried separately from the body. Conversely, Zomcon has created the domestication collar, when activated and placed on a zombie makes the zombie controllable and thus an eternally productive creature within society. Because all dead initially become zombies, the elderly are viewed negatively and suspectly. And all people, adult or child, learn to shoot to kill to protect society. Zomcon is the go to organization for all things zombie. In the town of Willard, the Robinsons - father Bill, mother Helen, and adolescent son Timmy - are one family who don't own a zombie as a domestic since Bill is afraid of zombies, as, when he was a child, he had to shoot his own zombie father, who tried to eat him. Bill has thus become fascinated with funerals to see zombies put away permanently. But Helen feels pressured to get a zombie when Zomcon's new head of security in Willard, the officious Jonathan Bottoms, moves into the neighborhood with his family. Never having had to deal with a zombie directly, Timmy is initially wary of their zombie. But as a lonely child who has no friends and is often bullied, Timmy eventually befriends their zombie, who he names Fido, as he treats the zombie much like a faithful pet dog. Timmy protects Fido at all cost, even after Fido, due to no fault of its own, is implicated in some deaths, which creates a mini-wave of loose zombies unknown to Zomcon. But Fido may play a larger role within the family as a companion for Helen, who is largely neglected by Bill, since he sees human affection as ultimately resulting in such difficult issues as what happened between him and his own father. With Timmy and Helen treating Fido with kindness, Fido, in turn, may prove that not all zombies, even when without their domestication collar, are out to kill anyone and everyone in their path.
Timmy Robinson's best friend in the whole wide world is a six-foot tall rotting zombie named Fido. But when FIDO eats the next-door neighbor, Mom and Dad hit the roof, and Timmy has to go to the ends of the earth to keep Fido a part of the family. A boy-and-his-dog movie for grown ups, "FIDO" will rip your heart out.
- In this satire of American society, we find ourselves following a little boy, Timmy Robinson (K'Sun Ray), through an alternate version of the white-bread 1950s of big shiny cars, houses with white picket fences, and prejudice, except that instead of Blacks there are zombie servants animated by space radiation, but kept under control with Zomcon zombie collars. Timmy is delighted with the family's first zombie (Billy Connolly), whom he names Fido, although his father, Bill Robinson (Dylan Baker), is terrified of zombies. the mother Helen (Carrie-Anne Moss) only acquired the domestic zombie due to social pressure from her neighbors. Bill is only interested in golf and in funeral rights to make sure that they will all stay dead when they die, and not become zombies themselves. Fido becomes Timmy's best friend, while the neighborhood playboy (Tim Blake Nelson) keeps a beautiful female zombie named Tammy (Sonja Bennett) as his girlfriend. Fido runs afoul of prejudice, circumstance, hardware faults in the Zomcon collars, and neighborhood bullies. Before we are done, there is murder and assorted other mayhem, zombification, a full-scale zombie riot at Zomcon, and the death of Timmy's father as a result of the zealous Zomcon security chief's (Henry Czerny) attempt to throw Timmy to the wild zombies beyond the fence to punish him for being attached to a zombie. Fido then rescues Timmy and all's well that ends well. Fido is restored to his family, and the widow discovers that she is happier with Fido than with her late emotionally challenged husband.
