A man murders his parents(?), then buries them in the backyard. For whatever reason, he sets up a television camera over their graves and watches them on the TV from inside the house.
A police officer, who figures out that the man murdered his parents, rushes to the house to make the arrest as the murdered parents begin to dig themselves out of the ground..., something the man in the house begins to witness on the tv.
Just as the officer breaks into the house, he sees on the tv, 3 sets of hands disappearing back into the ground.
