Cathy and Colin return from a luxury cruise strangely keen to persuade neighbours Eric and Beth to join them on their next trip.

The neighbours are woken in the night by a car alarm. After meeting Eric in the street, Colin and Christine invite themselves round.

Beth's hopes of a nice traditional Sunday lunch collapse when Cathy and Colin arrive arguing, Jaz locks himself in the toilet, and uninvited guests Christine and Sophie turn up to enjoy the lovely roast lamb and organic potatoes the Bairds have been preparing all morning.

Cathy invites the neighbours round to enjoy an extravagant spread of shop-bought nibbles to celebrate Colin's dad's birthday, but Beth has to step in and rescue the party.

Technophobe Christine faces a computer crisis when she goes online to buy a Barneyboo Buggy and her screen freezes. Beth has got more company at home in the shape of Ian and Jaz.

Beth hosts the perfect baby shower for Sophie but nobody seems to be taking it seriously. Jaz is sporting a black eye after a run-in with a packing box.
