Ronnie Corbett reunites with the writers of his hit series Sorry - Ian Davidson and Peter Vincent - for a sitcom about Sandy Hopper, a grandad happily growing old along with his dog Henry and his lodger, Dolores (Liza Tarbuck).

In this third episode, The Rival Grandad, we meet Sandy's grandson Tyson's other Grandad - Rex - who is a popular swashbuckling figure of a man, Tyson's hero and thus the bane of Sandy's life. Sandy's chance to get even comes when he takes Tyson and his sister Zoe to a new Adventure Park featuring dinosaurs, sharks and a great many light-fingered monkeys. Can Sandy's lodger, Dolores, save Sandy from an utter fiasco?
