Airlifted out of Vietnam on April 30, 1975, Doan Hoang's family was on the last civilian helicopter out of the country at the end of the war. Twenty-five years later, she sets out to uncover her family's story. The film follows her family as they return to Vietnam after decades of exile, where her father, a former South Vietnamese major, meets his brothers again to confront their political differences: one was a communist, the other a pacifist. Meanwhile, Hoang tries to reconcile her own difficult past with her half-sister, who was mistakenly separated from the family during the escape.
