Barbara Leen owns a coffee export company based in Rio de Janeiro. The company has long since been infiltrated by smugglers, without Barbara knowing about it. The criminals are smuggling diamonds. Barbara's boyfriend is a journalist and tries to get to the bottom of the matter. But during his research he comes across more and more deaths. Eventually, however, he comes across the nightclub owner Leila and her lover Dumont. They appear to be the masterminds.
