Island in the Sun (1957)

On a Caribbean island, a rich landowner's son, Maxwell Fleury, is fighting for political office against black labor leader David Boyeur. As if the contentious election weren't enough, there are plenty of scandals to go around: Boyeur has a secret white lover and Fleury's wife, Sylvia, is also having an affair. And then, of course, there's the small matter of a recently murdered aristocrat.
