Assistant manager Jonny has his hands full when a bunch of baby pine martens are brought in over the course of a couple of weeks. Jonny will need to use all his experience to bond these orphans into a family unit. If he is successful and can get them released, this charismatic mammal’s population will receive a really big boost. Elsewhere, one of Scotland’s more seldom seen creatures, a slow-worm, needs help from vet Liam to recover from a cat attack, the seal unit battle to release some of their charges, and a concussed woodpecker needs some TLC from the head of birds, Lorraine.
