Kit (Henry Golding), a young British Vietnamese man, returns to his birth country for the first time in over 30 years. He was just eight years old when he and his family escaped Saigon as 'boat refugees' after the Vietnam War. No longer familiar with this country and unable to speak his native language, Kit embarks on a personal journey from Saigon to Hanoi in search of a place to scatter his parents’ ashes. Along the way he meets his estranged family through Lee (David Tran) and falls for Lewis (Parker Sawyers), an American whose father had fought in the war.
