Ken Boon and Harry Crawford are two middle-aged ex-firemen. Harry retires and opens a hotel (The Grand Hotel), with Ken as a temporary odd-job man. During the seven seasons (1986-1992), Ken works his way up from odd-job man to private investigator, while Harry runs two hotels, a ballroom, a country club, and finally, a security firm. Over the years, they are assisted by Doreen Evans, Rocky Cassidy, Debbie Yates, Margaret Daly, Laura Marsh, and Alex Wilton.
