Luke is on his way to Lusaka, the bustling capital city, to work with a local dog charity. He goes on a patrol across town to crack down on the illegal practice of selling puppies on the streets; coming across young street vendor Richard who is given the opportunity to turn his life around. But will he take it? On the outskirts of town, Luke visits a wildlife sanctuary where he helps an abused baboon, greets a pack of lions, determines the sex of three infant Serval cats and tests some vervet monkeys for tuberculosis. After a bumpy flight to Kafue National Park, Luke investigates the mysterious death of over 30 buffaloes, before visiting an endearing elephant orphanage.
