The centre receives an unusual case: an otter from the very north of Shetland that has already failed twice to be successfully reintroduced to the wild.

Romain Pizzi, the centre’s chief vet, has to draw on all his years of experience and skills when he tries to save a vixen whose leg is in need of a life-saving operation. And the bird unit battle to save the life of a peregrine falcon with a gun shot wound.
