Alison and Larry are at the start of their B-road bimble from Billericay to Barry. They head to Epping Forest where they meet up with Billericay boy Russell Tovey, or 'Budgie' as he's known to the Gavin & Stacey faithful. With a bit of gentle persuasion Russell and Larry get Alison to join them on a unique looking electric bike and Russell reveals why Gavin is from Billericay.

On the second leg of their tour to Barry, Alison and Larry get lost in the maze at Blenheim Palace, and try puppet making with old friend Robert Wilfort, who played Stacey's brother Jason. In the snowy South West, Larry takes a cold dip, and on the way to Bath, tells Alison about his unsuccessful attempts at auditioning for James Bond.

On the final leg of their B-road tour to Barry, Alison and Larry join an all-male Welsh choir and attempt to sing in Welsh.
