The true story of Assis Chateaubriand, the first magnate of communications in Brazil. Due to his influence during the late 1930s up to the early 1960s, he has come to be called 'the Brazilian Citizen Kane'.

The Tatu Tatuado de Topázio ring, by socialite Gracinha de Medeiros, is on display at a museum. She then hires the clumsy security guards Pedrão and Jorginho to watch over the jewel, a family heirloom. The ring is stolen and the pair accused of theft. To prove that they are innocent, they will have to face Portuguese mobsters and a gang of ninjas.
