Follows the wavering relationship between two ex-lovers, Penny Warrender, a secretary for an advertising firm, and Vincent Pinner, an ex ice-cream salesman turned Turf Accountant Bookmaker who is also the son of a wealthy scrap metal merchant. The couple has split up following Vincent's decision not to marry Penny on their wedding day, leaving her at the altar. In the pilot episode, five years since their intended wedding day, the pair meet again by chance in a pub while out on individual dates. The pair decide to forget the past and become friends, although the rekindling of their relationship is not welcomed by Penny's snobbish parents, particularly her mother, Daphne, played by Sylvia Kay.
