Big screen adaptation of Jack Rosenthal's sitcom following a pair of young lovers struggling to find happiness in 1970s Manchester. The primary area of conflict between Geoffrey Scrimshaw (Richard Beckinsale) and Beryl Battersby (Paula Wilcox) regards sex, which Geoffrey is keen to try and Beryl, who has been brought up with strict, old-fashioned values, recoils from. Geoffrey is eager to point out that they're living in the 1970s, a more permissive age, but will this convince Beryl - who refers to the act as 'Percy Filth' - to submit to his desires?
