These adaptations of four 1974 episodes of the BBC1 comedy series The Liver Birds feature two incompatible Liverpudlian girls, Beryl and Sandra. What they have in common are a tiny flat, boyfriend problems, and a passion for the latest fashion. In the title episode, it's Beryl's birthday, and Sandra is planning a surprise party for her. Among her presents she gets a hamster in the post from Robert - but then Thingy goes missing, and the hunt is on to find the rogue rodent. Starring Polly James and Nerys Hughes.
