On the back of the Wall Street Crash of 1929, a young businessman is about to commit suicide. With a note to his wife scribbled down and a gun in his hand, he notices an envelope addressed to him on his desk. As he begins to read, we're taken back to World War One and his meeting with a young woman named Mary Lane.

According to a legend, the mansion's "blue room" is cursed -- everyone who has ever spent the night in that room has met with an untimely end. The three suitors of the heroine wager that each can survive a night in the forbidding blue room.
