Arriving in Rio to tour the local cosmetic surgery clinics, a respected British esthetic surgeon, Charlotte warns potential clients that rhinoplasty isn't the key to true happiness. Meanwhile, out on the streets, a visiting U.S. ambassador, William gives his handlers the slip, and disappears into the city's most dangerous favela- slum or shantytown, especially in Brazil. There, he befriends a free-spirited tour guide and his gorgeous partner, who open his eyes to a side of the city few tourists ever see.
