It’s Gwen’s birthday and Bryn has arranged a special surprise treat, although the stress of organising it is starting to get the better of him and arouse Gwen’s suspicions, as the hit comedy series continues. Then, an uninvited guest turns up and Stacey tells Gavin of her big decision.

Gwen is played by Melanie Walters, Bryn by Rob Brydon, Stacey by Joanna Page and Gavin by Mathew Horne. James Corden, Ruth Jones, Alison Steadman and Larry Lamb also star.
