Barbara and Ted return from holiday,Ted having broken his leg retrieving their luggage from the airport carousel. They find Neil head over heels in love with pizza delivery girl Kirsty,even though she is bossy and - to Barbara's mind - dirty. Martin has been having a run of bad luck and is surprised to meet his ex-girlfriend,who just happens to be Kirsty. Kirsty is still very much in love with Martin and decides that she cannot love another so she dumps Neil - much to Barbara's relief.
