As the title suggests, the baby-sitter (an old woman) is found dead in a chair. When Sue Ellen calls her name and tries to tap her, she falls to the ground, completely lifeless.
The kids cover the baby-sitter's body, drag her to the car, put her in a trunk, and drop her off at the front door of a mortuary. The trunk has a note on it that says "Nice Old Lady Inside. Died of Natural Causes."
One of the kids falls out of a tree and breaks his leg. We see him lying on the ground in pain. He is taken to the hospital.
