In the first episode of a new series, the family are surprised to find out that Leslie has three different girlfriends, so Louisa decides to take it upon herself to help him pick one by having each member of the family invite their favourite girl to afternoon tea. Larry injures his leg and Theo decides to use his newly set-up x-ray unit to try and examine it. Elsewhere, Gerry continues to grow his animal collection, Margo takes up a job as Theo’s assistant, and Aunt Hermione arrives in Corfu for good.
