Kate Humble and her Welsh sheepdog Teg continue their journey across the remote Welsh countryside, by exploring Carmarthenshire. In the Cothi Valley, Kate herds and milks goats. In Capel Iwan, Kate tries her hand at trotting. Then in Cwm Elfed, they meet an Englishman keeping the Welsh weaving tradition alive. Near Carmarthen, they see how beavers are transforming a Welsh farm and in Llansteffan, they take to the water, rowing across the Towy estuary to reach the end of their journey
