Cathy and Colin have returned from a luxury cruise and seem strangely keen to persuade neighbours Eric and Beth to join them on their next trip. However, it soon transpires they have an ulterior motive - getting hold of a cheap deal. With Eric and Beth politely declining, the determined couple have another target in mind. Christine, fresh from a PPI refund windfall, wants to crow about her good fortune, and Beth is railroaded into holding a celebratory barbecue - the perfect moment for the holiday hunters to pounce.
The neighbours are woken in the middle of the night when a car alarm goes off. After meeting Eric in the street whilst searching for the source of the noise, Colin and Christine invite themselves to the Baird's for a cup of tea, with Cathy and Sophie not far behind. Soon, an impromptu late night party is underway, despite the unwilling hosts just wanting to go to their beds.
Beth's hopes of a nice traditional Sunday lunch collapse when Cathy and Colin arrive in the midst of an argument, 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 posh shop-bought nibbles to celebrate Colin's dad's birthday. Despite her big show of being the ultimate hostess, long-suffering Beth has to step in and rescue the party. Birthday boy Willie isn't impressed by any of it, but finally gets into the party spirit when Colin presents him with his old accordion.
Technophobe Christine faces a computer crisis when she goes online to buy a Barneyboo Buggy for Sophie's baby and her screen freezes mid-purchase. She heads to the Bairds to get help. Beth has got more company at home in the shape of Ian and Jaz, who are staying while they wait to pick up keys for their new flat, and footie fans Colin and Eric are getting excited about their trip to watch Scotland play in Latvia.
Beth has organised the perfect baby shower for mum-to-be Sophie. Everyone is invited and Christine has even asked Pat from over the back, who she is assuming is going to be the baby's godmother. Sophie, however, has already asked Beth and Eric and hasn't yet broken the news to her mum. Jaz is sporting a black eye after a run-in with a packing box, and whilst Cathy is excited by the idea of a party, she doesn't want to get too close to Sophie in case the birth happens earlier than expected.
Cathy's jealousy over Colin's ex-girlfriend nearly derails Burns Night. Not everyone is enthusiastic about eating haggis, least of all vegetarian Gordon.
Back from a quiz night at the pub, everyone is encouraged to reveal their hidden talents. Cathy is very bendy but Gordon not quite as agile as everyone had hoped.
The new couple on the street are invited to Beth's to meet the neighbours. Everyone warms to them except for Cathy, whose competitive instincts get a little out of hand.
Beth and Eric think their son Ian is taking them out for their 30th wedding anniversary dinner - but find instead that he and his boyfriend Gordon have organised a surprise party at their house. And the gang’s all there.
Beth has cooked a curry for Ian and Gordon’s anniversary, but there’s no such thing as a quiet family meal, what with the neighbours inviting themselves over and completely hijacking the occasion.
Beth is ill in bed and in desperate need of some rest. But the neighbours have decided Eric isn’t coping and are convinced they know how to nurse Beth back to health.
Colin is vulnerable after being unceremoniously dumped. Beth and Eric are doing their best, but conversation is already strained when Christine steams in demanding gory details.
Alan is laid up on the sofa after an accident. Beth and Eric are looking after him when Christine arrives with goodies, and Colin can’t wait to share details of internet dates.
There's great excitement as Colin introduces the neighbours to his new partner, Anne Marie. But the gang are quickly taken aback by her enthusiastic approach to the dinner party.
Beth and Eric are throwing Christine a 69th birthday party, but the celebration gets usurped by chat about a funeral, which leads Christine to start thinking about her own.
Chaos ensues as Ian and Gordon’s pals park up at Beth and Eric’s for their Aussie holiday, and an organised Morven becomes increasingly tense with Lin’s lack of packing skills.
Taking advantage of the weather, the neighbours head for the back garden, but it’s hardly relaxing as Beth fields criticisms of everything from her garden furniture to her slabs.
Over at Colin's house, the neighbours are gathered for a surprise birthday party for Anne Marie. But when the doorbell goes, it's Colin who gets the big surprise.
A new bathroom is a big commitment, and Christine can’t decide, driving Beth and Eric demented. Meanwhile, Cathy and Michelle bond over a boozy lunch, but will this new friendship last?
Ian's school friend Darren turns up out the blue sparking many memories - and when the neighbours probe into their past relationship, Gordon finds himself in a spiral of paranoia.
It's Father's Day at the Carvery for Ian, Gordon, their parents and Christine, who wangled an invitation. As she grumps about the beef, Gordon grapples with family revelations.

Alan and Michelle are bleary-eyed off a delayed flight from Las Vegas. They’ve got big news to share with the neighbours, but their exciting announcement gets quickly out of hand.
