Kia planned to have some fun with her boyfriend, Grant, out in the woods. Plenty of nature and peace to help make their clothes fall off. A simple enough plan. Until they arrive and Grant reveals there are five other couples joining them. Worse still, they all seem to know one another. Worse still, they start telling ghost stories. As the night wears on, and she drinks more than she should have, they decide to check out a local haunted house after one of the boy's reveals its checkered past. The couples split apart in the old house, each taking a room to themselves for a little fun. She and Grant finally get some time to get busy, but shortly after she finds herself sick, her stomach cramping and bloating. Before long, her belly begins to grow. Not just her, either, the other girls are growing too. Their bellies swelling, things moving inside them. Kia tries to escape, but her belly makes fleeing back through the woods easier said than done. She has to find help, somehow, before the thing growing inside her is ready to be born.
