In 1958, the Laemle family—father Nick, [Randy Quaid], mother Lily, [Mary Beth Hurt], and their 10-year-old son Michael, [Bryan Madorsky]—moves from Massachusetts to a quiet Californian suburb, trading the bustle of city life for the unsettling calm of a white-penced neighborhood. Michael, a socially awkward boy with a vividly active imagination, struggles to make friends at school and is haunted by dreams that feel almost real, including a disturbing vision where he jumps into bed only for it to split into a pool of blood.
Emotionally overwhelmed by the move and these dreams, Michael becomes traumatized after a series of troubling experiences. He accidentally witnesses his parents having sex, which he misinterprets as them biting into one another, and he glimpses his father performing a disquieting act—cutting into a corpse in the Division of Human Testing at Toxico, where Nick is developing an Agent Orange–style defoliant for use in jungles. This combination of fear and confusion deepens his sense that something horrifying lurks beneath the family’s ordinary exterior.
As time goes on, Michael grows convinced that his parents are cannibals. The belief intensifies when he encounters, or dreams that he encounters, dismembered body parts hanging on a meat hook in the basement. The idea consumes him, and his distrust of reality worries Millie Dew, the school guidance counselor. Millie, [Deborah Rush], tries to reason with him and reassure him that his fears may be a fantasy born of stress rather than truth, but the evidence around him only seems to mount.
One afternoon, Millie accompanies Michael to her home so she can help him see the situation more clearly, but the two of them discover a corpse in the basement. Panic erupts as Michael flees to his room while Millie is killed after being forced into the pantry, a shocking reminder that danger can lurk even in moments of supposed safety.
When Nick and Lily return, Michael confronts his father in a tense showdown. Nick responds with violence, attempting to feed Michael what could be human meat, insisting that he will grow to enjoy it as his mother does. Michael fights back and drives a stab into Nick’s shoulder. Nick retaliates in a desperate bid to kill his son, but Lily sacrifices herself to protect Michael and dies in the process. The confrontation crescendos as Nick, gravely injured, causes a gas leak and inadvertently triggers a chain of accidents that lead to a catastrophic explosion: a shelf of wine bottles collapses, and the room fills with gas just as a blast erupts, leaving Michael with a slim chance to escape.
In the aftermath, Michael is left in the care of his paternal grandparents, who tuck him into bed and leave a late-night snack—a suspicious-looking meat sandwich—on the table. The closing image lingers on a troubling suggestion: perhaps the nightmare isn’t over, and the cycle of cannibalism may trace back through the family line, hinting at a dark inheritance that stretches beyond the confines of the house.
