Deco and his best pal Naldinho are co-owners a small cargo boat. They give 20-year-old Karinna a ride down the coast, paying for her services along the way. At a cock fight in a coastal town, a brawl breaks out and Naldinho is nearly killed. Deco defends his friend, and, while nursing him back to health, falls hard for the ever-available Karinna. At first, Naldinho teases Deco about giving his heart to a whore, but in the end he finds himself just as infatuated. Jealousy separates the trio, then desire brings them back together.
