In 1962, a U.S. soldier deserted his unit and walked across the heavily fortified border area to defect to the Cold War enemy, the communist state of North Korea. He became a coveted star of the North Korean propaganda machine and acted in films. Now, after 45 years, his story is finally told.

This documentary about South Korea finds director Daniel Gordon returning to this closed-off country to explore not its original citizens but rather, shockingly, American defectors. Granted rare access, Gordon rides a thin line to not aggravate his hosts, but the results are still fascinating.
