PT 109 (1963)

Dramatization of President John F. Kennedy's WWII military experiences during which he commanded a PT boat that sank after being rammed by a Japanese destroyer while on patrol in the South Pacific on a very dark night. He and the other survivors, some of whom were wounded, made their way to a nearby island where they had to survive on meager rations and avoid capture by enemy forces till they could find a way to signal the Navy for rescue.
