Charley begins in Cape Town and abseils from the summit of Table Mountain before crossing shark-infested waters to Robben Island, where Nelson Mandela was incarcerated for 18 years. At Gansbaai, he cage-dives while great white sharks are fed bait, then makes his way up the coast to the Shamwari Wildlife Reserve, where he is introduced to some of the lions and leopards rescued by the Born Free Foundation.
