For centuries the Cuckmere River has inspired artists, sheltered smugglers and preserved a host of rare habitats and wildlife as it charts a course through some of the most evocative landscapes in southern England.

In a work of beauty and eloquence, the filmmaker Cesca Eaton and the composer/conductor Ed Hughes trace the changing moods of the Cuckmere river, from its source in the Sussex Downs to its dramatic twists and turns as it meanders to the sea at Cuckmere Haven.
