A cat burglar named Trilby goes to a large mansion called DeFoe Manor, in hopes of an easy score of expensive loot, as the owners had died shortly beforehand. However, Trilby finds himself inexplicably sealed inside the house, along with four other people, who had come to the manor for various reasons of their own. The story progresses over 5 days, with more story being revealed each day. Dream sequences typically space out the transitions between the events of different days.
