An intelligent electric current flows from room to room. It intimidates the residents of the house by controlling various instruments, either killing them or destroying the house. Then it ran through the wire to the next house and began a new round of intimidation. As soon as one quiet house was destroyed, the current was connected to the next one. The owner of the house is a divorced father and his son. Here, the electric current slowly controls all objects, and then seriously injures the child's stepmother. Now it is setting traps for the child and his father, and they need to try their best to find a way to escape.
