Demi gets in trouble at school for not paying attention. Her teacher warns her that she could be "in peril" but Demi doesn't think much of it. Later, Demi receives a cryptic text warning her to remember what she heard. Demi and her friends go to play at the park but Amy dares them to enter a nearby cave. Inside the cave, a ghostly figure appears that horrifies Demi - it is the ghost of her dead mother. Fifteen years later, Demi remains trapped in a room with the rotting bodies of her friends, with only monthly visits from her mother's ghost.
