Come here, children, play with me, I'm the friend in your TV... The Calvert family's new home used to belong to the recently deceased creator of a forgotten children's program from the early days of television. The family's younger kids are fascinated by the basement rooms, a chaotic wonderland of discarded stage sets, props, costumes, and puppets. At first, the parents are glad to see the kids put down their screens and play creatively with the old theatrical elements, but their performances and their experiences grow more disturbing over time. In this house, the reruns of a dark past never stop playing, and paranormal investigator Ellie Jordan must protect the family from a malevolent presence trying to draw them into the infernal show.
