After being phone buddies for months, Gavin and Stacey finally arrange a rendezvous in Leicester Square, with Stacey's best friend Nessa and Gav's pal Smithy coming along for support.
After a huge misunderstanding on the phone, Stacey thinks Gavin has finished with her. He drives to Wales to explain and ends up taking her home with him. Having never been further than Bridgend before, Stacey's trip to Essex is an eye-opening experience that ends with the biggest surprise of all.
After his initial angry reaction to Stacey's news, Uncle Bryn agrees to drive them all to Essex to meet the Shipmans. Pam has laid on a cracking spread and the party goes with a bang. But then Gavin and Stacey make an announcement that throws all the bonhomie out the window.
The Shipmans drive down to Wales for the wedding fayre. After an eventful trip to church to hear the banns being read, Nessa confides in Stacey her big secret.
Stacey's brother Jason arrives home early, much to Uncle Bryn's horror. Stacey has her hen night and Gavin has two stag nights, the second of which reveals something about Stacey that could jeopardise the whole wedding.
The wedding day has finally arrived, but will they go through with it? Will Uncle Bryn finally admit to what happened on the fishing trip and will Nessa do what she knows she must?
Stacey and Gavin return from honeymoon to a big welcome from both families. But Smithy seems none too happy with his best mate and Nessa has a confession to make that throws the whole evening into disarray.
Devastated by the news he's to become a father, Smithy goes AWOL. The boys finally track him down, but can he be persuaded to do the right thing? Stacey is shocked to hear of Gwen's new domestic arrangements as the prospect of living in Essex finally hits her.
Stacey feels dejected because she cannot get a job and Pam tells her she needs to get out more. Smithy needs Gavin's shoulder to cry on because his girlfriend split with him over Nessa's pregnancy and told him she was seeing a younger man anyway. Gavin, Stacey and Smithy head for Barry so that Smithy can go for the scan with Nessa. Smithy lodges with Bryn, who has turned his spare room into a gym and sets about getting Smithy into shape.
Stacey is miserable and homesick because she still hasn't got a job, or her own home. She feels she's getting under everyone's feet, especially when Pam interrupts her during her shower. Gavin tries to console her but she says he just doesn't understand. Pam admits to Dawn that having the newlyweds staying in her house is getting a bit much. (Dawn and Pete are still looking for a threesome.) Gavin and Stacey go to view a potential flat and are shown round a tiny, dirty studio by over-enthusiastic estate agent Duncan.
Stacey and Gavin are still in conflict over where they should live…with Gavin refusing to even consider the idea of living in Barry. Smithy admits to Gavin that he had another fling with Nessa and realises he's going to have to face her again at the surprise party Bryn is throwing for Gwen. Bryn is panicking because he wants to keep the surprise barn-dance themed party a surprise…but he's also having trouble getting enough people to attend.
Gavin seeks counselling for his marriage troubles from Smithy, but Smithy’s idea of relationship therapy is to organise a surprise lads night out at a nightclub foam party. While the lads are knee deep in foam, Stacey is with her family at a bingo night.
Stacey travels to Essex and back into the arms of Gavin. Everything seems perfect until Pam and Mick offer to cover the down payment on a house for Gavin and Stacey. Stacey tells Gavin that it can’t work between them because they both need to live in their own towns. If they were truly meant to be together, this wouldn’t matter, they would even think about it…but that clearly isn’t the case. She gives him her wedding ring back...
As Nessa and the Wests head to Essex to spend Christmas with the Shipmans, Gavin and Stacey have a startling announcement to make.
Gavin starts his new job in Cardiff and Stacey is thrilled to be at home again. Smithy comes to terms with life in Essex without his best mate, whilst Nessa is adjusting to life in Dave's caravan down Sully. The weekend brings with it a big reunion, as everyone meets up for the christening of baby Neil. But how will Smithy react to news from Nessa that it is a double celebration? And what will Gavin's answer be to Stacey's request?
Stacey is trying for a new job whilst ensuring Gavin sticks to his recent promise! Dave is not a happy bunny when Nessa tells him she is taking Neil the baby to Essex to see his dad. Meanwhile, over at the Shipman's house, Dawn and Pete have joined Pam and Mick for a beer-and-curry night of huge proportions - at the Billericay house of fun.
Pam and Mick are having second thoughts about the conservatory, whilst Bryn is in his element as he awaits the arrival of his house-guests - all the Essex boys down for a big night out in Cardiff - and having a sleep-over at his place! Smithy gets in a state about seeing Nessa after their most recent embarrassing meeting, and Stacey makes a worrying discovery. But is telling Gavin the right thing to do?
Gavin is uncomfortable with Gwen and Bryn knowing the ins and outs of his and Stacey's sex life, and Smithy goes beyond the call of friendship by making a staggering suggestion. Meanwhile, Pete and Dawn prepare to renew their wedding vows and everyone heads to Billericay to help them celebrate. But how will Dave react to the bombshell revelation about the curry night in Essex?
It's Bank Holiday Monday, and the Essex contingent arrives for a sunny day out at the beach - even Doris is wearing her sundress! Gavin's heart-to-heart with his dad gives him something more to think about, and a dark cloud looms on the horizon when Dave arrives to find Nessa and Smithy enjoying all the fun of the fair.
Nessa and Dave's wedding is fast approaching and the preparations are in full swing. Stacey breaks some life-changing news to Gavin, whilst Bryn and Jason finally put their big secret to bed. Smithy takes care of Neil the baby and wishes Nessa all the best, as she makes her way to the church to marry Dave.
The families get together once again for Christmas. Bryn is cooking dinner, Dawn is in shock, and there are revelations in the pub on Christmas Eve.
