This week the Brennans are challenged by an Irishman and an American who have gone into business together. Stephen McPhilemy is an Irish tour guide and co-owner Patrick Wade is a pharmaceuticals entrepreneur. They recently bought Milltown House in Dingle, Co Kerry. The 10-bedroom guesthouse has Hollywood connections as it was once rented by Robert Mitchum. Stephen and Patrick have ambitions to make this one of the finest guesthouses in Dingle. However, there's an awful lot of work to be done and they have no experience. Can the Brennans make this Irish-American dream come true?
