Writer and fisherman Will Millard tells the extraordinary story of how the River Taff came back from the dead.
This river, once so polluted by heavy industry that no fish could live there, has now become one of the best salmon and trout rivers in Wales. Will travels from the source high in the stunning Brecon Beacons National Park to Merthyr Tydfil and the Bristol Channel.
Along the way he trains with a mountain rescue team, meets a group of conservationists working to protect a magical, hidden valley and sets out to catch The King of the Fish: salmon. He also explores how the coal industry impacted on the beautiful landscape and meets retired Somali sailors drawn to Cardiff in the city’s glory days as a thriving port.
