Billy Lynn (Joe Alwyn), 19, is sent home to Texas after a heroic act in Iraq. Along with seven fellow soldiers, they go on a two week "Victory Tour" of the States.
As the tour unfolds, Billy increasingly becomes more disenchanted with how war heroes are treated. Through various flashbacks, culminating at the halftime show of a Thanksgiving Day football game with a performance by Destiny's Child, we discover secrets from Billy's past and exactly what happened to Billy and his Bravo Squad while in Iraq.
His sister Kathryn (Kristen Stewart) notices that Billy has signs of PTSD and tries to convince him to seek help, but he's torn between taking her advice, or upholding his image as a "hero," which means returning to Iraq.
Based on the bestselling novel of the same name by Ben Fountain.
