On a sweltering summer night, a black plane, flying dark, crashes on a small island off the coast of Georgia. Constable Delmont Grove, the island's only law, (and the only one to witness the crash) undertakes an investigation into the origin and purpose of the clandestine flight. As events unfold, trouble comes to the island, in the form of the plane's owner, determined to recover his property at any cost. The residents of the island face dangers that require them to depend on each other for protection, and even survival.
