After being phone buddies for months they 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, her 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 everyone 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 Shipman's and Smithy travel to Barry Island for the wedding preparations; Gavin has to choose between the horse and carriage that Stacey wants or the Bentley that he wants; and Nessa thinks she might be pregnant
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 whether they will go through with it is another matter; Uncle Bryn may finally admit what happened on the fishing trip; Nessa is conflicted.
