Filmmakers Charlie Hamilton-James and Philippa Forrester went in search of otters on a short stretch of the River Torridge in Devon, immortalised 80 years ago by Henry Williamson in his famous novel Tarka the Otter. Over months of patient fieldwork they got to know and film a family of wild otters. The result is both a lyrical portrait of these shy creatures and a tribute to Williamson's skills as a writer and naturalist.
