Robert Irvine tries to save a piece of history in Garrettsville, Ohio, by rescuing a restaurant in a 200-year-old mill. Shelli, the owner of Garrett's Mill Brewing Co., is in over her head after her husband had to return to his trucking job to keep the business afloat. They have a $500,000 payment coming due, and the historic mill is just months away from grinding to a halt.
