Samba, the Smugglers from Rio

Brazilian singer Laura Monteiro is murdered in her dressing-room by her jealous lover Joao Fernandes de Oliveira when he discovered she was cheating on his with Assis and planning to escape from him and go to Buenos Aires with Assis. Meanwhile, Belen Moreira, who lives in Favela do Salgueiro and is a dead ringer for Laura, goes to Copacabana with her boyfriend Paulo. Two members of a gang that smuggles precious stones sewn in Carnival costumes see Belen and force the President of the Salgueiro Samba School to invite her to perform Chica da Silva in the Carnival parade in a costume that is adorned with genuine precious stones to be smuggled to Europe.
