Nineteen-year-old soldier Billy Lynn (newcomer Joe Alwyn, perfectly cast) performs a heroic deed in Iraq that was caught on camera and went viral. As a result, he and his Bravo Company are temporarily brought back to the States halfway through their tour to take part in a mindless, rah-rah halftime show at a Thanksgiving football game.
