Kristen returns home for summer break to see her family. Her little sister Katy mentions that she's heard creaking at night while Kristen was gone. Kristen laughs at the thought of a monster under her bed, but when she's left alone in the middle of the day, she hears the creaking as well. It may not have been a good idea to laugh off the horny monster under her bed...
Kristen might end up enjoying her summer break more than she thought she would.
