All six episodes from the fourth series of the ITV drama based on the memoirs of British naturalist Gerald Durrell. Set in the 1930s, the series follows widowed matriarch Louisa Durrell (Keeley Hawes) as she makes the life-changing decision to move with her four children from their home in Bournemouth to the Greek island of Corfu in search of a better life. While young Gerry (Milo Parker) uses the opportunity to indulge in his growing love of nature, his older siblings, Leslie, Margo and Larry (Callum Woodhouse, Daisy Waterstone and Josh O'Connor), search for love and friendship as they attempt to start over on the island. In this series, the family prepares to turn their home into a guest house and Gerry decides he is going to open a zoo.
