On the 50th anniversary of the miners' strikes, Matt Baker and Anita Rani are in County Durham on the Heritage Coast to discover how this area has risen from the ashes and reinvented itself after pit closures. Matt finds out how a colliery has become a nature reserve, and Anita discovers how one pit is now enjoying a new lease of life as a source for cutting-edge clean, green energy. Also, Tom Heap investigates the hidden threat facing countryside communities living in the shadow of our mining past, and Adam Henson sees how the avian flu crisis is threatening the livelihood of free range egg farmers.
