"PT 109" is a movie based on the real-life wartime experiences of John F. Kennedy. In 1947, Kennedy was a young naval officer who obtained command of his own PT boat during World War II. The story centers on the man who was elected president of the United States in 1960. Few movies have ever timed their release better. The plot centers on Kennedy's boat, the crew and the command. During an encounter, his PT boat is destroyed by a Japanese ship. The surviving PT crew members swim to an island, which is under Japanese command. They avoid capture and eventually return to the States. A pretty simple story, but stories of bravery are many times very simple.
