Sammi Kinghorn and Matt Baker are exploring the waterways of the Shropshire Hills, where the critically endangered Atlantic salmon makes its ancient journey upstream to its spawning grounds.

Sammi and Matt meet the people of Shropshire, from ecologists reshaping rivers to farmers maintaining clean waterways, as well as an artist crafting steel fish. Together, they work to raise awareness about the importance of preserving these rivers for the salmon and the many species that depend on them.

Meanwhile, in the Cotswolds, Adam reflects on a challenging year on his farm and plans for the year ahead.
