A Return to the End follows a small group of Marine Security Guards (MSG’s) as they travel back to Vietnam to honor the last two casualties of the war, Charles McMahon and Darwin Judge. On April 30, 1975, after helping thousands of Vietnamese civilians evacuate, these Marines were on the last helicopter that left from the roof of the U.S. Embassy.  After 40 years, they return to Vietnam to honor the two men who didn't make it back.
