Jon and Lucy are invited round to their 5-year-old neighbour's birthday party and Lucy insists that Jon tries to at least look like he's enjoying himself. Jon signs up with a new GP who's a bit too pleased to have a new celebrity patient.
Lucy hears from a famous fan of the show who wants to meet up and find out more about Meet the Richardsons. Jon and Lucy smell a rat and plot to unmask the secret copycat couple.
Meanwhile, old neighbours, Emma and Damion pay a visit and offer their opinion of Jon and Lucy's new next-door neighbours. Jon needs an escape route and makes a big decision about an old unloved local pub.
