Comedians Elis James and Miles Jupp take a series of unconventional trips around Wales. Carmarthen is the starting point as Elis and Miles board the good ship Carolina and sail from the town centre down the Towy river and out to sea. Their destination is Laugharne, famous for its association with Dylan Thomas. After a visit to the Dylan Thomas boathouse and his tiny writing shed, they retire to the bar of Brown's Hotel where Elis comes up with a brand new TV format. The following day they head to Pendine, where many land speed records were set during the 1920s and 30s. Later, with varying degrees of enthusiasm, the two travellers try out camping for the night in a nearby holiday park, then set off the next day for another river trip - this time up the Cleddau river towards the tiny hamlet of Coedcanlas, to meet beekeeper Nick Tonkin and his family.
