Ben arrives in the capital Brazzaville, before setting off into the wilderness to visit a remote tribe living deep in the jungle - the semi nomadi Mbendjele BaYaka, who have never been filmed before.
On the second leg of his journey, Ben visits a market selling threatened species for food, and heads deeper into the Congo wilderness to fulfil his dream of seeing wild gorillas.
Ben's final leg takes in daredevil fishing, where over a million cubic feet of water flow every second, and Congolese wrestling - in which fighters set themselves on fire, brandish live snakes and eat bottles.
