The escape room is a re-creation of the whiskey smuggling era. Amy Sharpe is murdered and all of the people at the Castle are suspects. Constable Kurt Spencer investigates and he is smitten by Lynette. Suddenly a storm knocks out the electricity and surrounding roads are washed out. All of the people, including the murderer have to stay at the Castle overnight. Constable Spencer and Detective Wilton investigate the murder and learn that Candace Stewart is the main suspect. Candace is Maxine Swayman's cousin and there is friction between the police officer and the lawyer. Another murder occurs, and Candace was out of the country when it happened. Have they arrested the wrong person?
