A man returning from a trip is invited to stay in his best friend's residence. There, he meets the man's wife and soon a love affair begins. With a great sense of enthusiasm he shares to his friend that he's deeply in love with a woman he just met, creating a great sense of curiosity on the other, barely knowing that the woman is actually his wife.
The legend of Tristan and Isolde is one of the most beautiful love epics ever conceived. Richard Wagner, in a famous opera, had already tarnished its purity. The modern transposition of the legend is set in Brazil, in a village of poor fishermen on Guanabara Bay, framed by mountains not far from Rio de Janeiro. Two young cousins, Marcos and Jeronimo, get together to fish successfully - the arrastao is a large fishing net - and to resist the ugly local landowner, who sets the rules and the prices. This owner has a niece: Emaïsa, who loves Marcos and is loved by him.
A young man must choose between two women. The one brings him the money, but the other he loves.
