Luke Gamble cut his teeth as a mixed practice vet in the West Country. Now it's time to see if he can stand on his own two feet. Wild stallions, drowning cows and constipated snakes aside, Luke's challenges have only just begun. No longer working at the West Country clinic, he's marrying the girl of his dreams while launching his own practice, Pilgrims. On top of that, he's managing his international veterinary charity and two other veterinary businesses. On his extreme travels around the world, Luke dodges hippos and chimps, and swaps the familiar farms of home for the refugee camps of Africa, all on his idealistic quest to make a difference. But Luke is more than just an international vet. He's also a husband, a friend, an entrepreneur and, potentially, an Ironman triathlete. Does he have what it takes to juggle it all?
