Toys of Terror follows the story of a family of six who decide to escape the hustle and bustle of the city during the holidays by renting a large, isolated house in the snowy woods of Washington. Upon arriving in the old, dusty house, the family discovers a collection of old toys in the attic that belonged to a boy named Dario, who died in the house many years ago.
As the family settles into their new home, they begin to experience strange occurrences that become increasingly unsettling. Young Hannah, one of the family's daughters, becomes particularly obsessed with the old toys, while her brother David begins having nightmares about Dario.
As the supernatural occurrences become more frequent and more violent, the family begins to realize that something darker and more dangerous is at play. They eventually discover that Dario's ghost is haunting the house and that the old toys are actually cursed items that possess a malevolent power of their own.
As the family fights for survival against the increasingly aggressive ghost and the dangerous toys that come to life in the night, they must work together to uncover the truth about Dario's death and find a way to break the curse before it's too late.
