In 1594 in Brazil, the Tupinambás Indians are friends of the French and their enemies are the Tupiniquins, friends of the Portuguese. A Frenchman (Arduíno Colassanti) is captured by the Tupinambás, and in spite of his trial to convince them that he is French, they believe he is Portuguese. The Frenchman becomes their slave, and maritally lives with Seboipepe (Ana Maria Magalhães).
