On the second leg of his epic round-the-world journey, Sir Peter Ustinov touches down in Hawaii, Australia and New Zealand. In this exhilarating episode, he's intrigued by people's ancestry; by their obsession with roots, and by the damage inflicted by history. It's a curiosity which finds him in some memorable situations; stark-naked in a hot thermal bath; grimacing at a Maori facial tattoo parlour; discussing budgies on a Sydney ferry and leprosy on a remote Hawaiian peninsula.
