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’ during the Vietnam-American 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 and falls for Lewis, an American whose father had fought in the war. During his travels, Kit finally starts to connect to the memories of his parents and his own roots.
