Whatever is happening in the outside world, life in Colchester zoo goes on. Curator Sarah Forsyth is heading into the busiest summer of her life keeping countless animals happy while four out of five of her keeping staff are furloughed. Sarah lives on site - the animals are her family - and they have never needed her more. This documentary follows Sarah for two animal-action-packed weeks, entirely inside the walls of one of Britain's largest zoos as she works tirelessly to deal with the summer baby boom, animal emergencies and unique situations created by the absence of paying public.
