You're Connor, a college student on a trip through an enormous, rather odd renaissance-era palace. Your girlfriend Harley gets a bit bored wandering around with the class and your droning professor, so she decided to wander off. It's up to you to follow her, and to decide how far you're willing to follow her. The palace holds many secrets.
