The central theme of the soap opera is the struggle for political control in the interior of Bahia between the two most powerful *coronéis* (landowning bosses) of the cocoa region: Sinhô Badaró and Horácio da Silveira. Virgílio, an ambitious lawyer, is summoned to the town by Colonel Horácio but ends up becoming involved with Ester, the colonel's wife. Captain João Magalhães is a card sharp who poses as a military engineer, successfully deceiving the entire town. He falls in love with Sinhô Badaró's daughter, Donana. By the end of the story, he reveals that he had only gotten close to the Badarós out of opportunism. After numerous clashes with Sinhô Badaró, Colonel Horácio secures political power in the town of Ferradas, with the acknowledgment of the local population.
