In 1975, as the Vietnam War was ending, thousands of orphans and Amerasian children were brought to the United States as part of "Operation Babylift." tells the dramatic story of one of these children, Heidi Bub (a.k.a. Mai Thi Hiep), and her Vietnamese mother, Mai Thi Kim, separated at the war's end and reunited 22 years later. Heidi, now living in Tennessee - a married woman with kids - had always dreamt of a joyful reunion. When she ventures to Vietnam to meet her mother, she unknowingly embarks on an emotional pilgrimage that spans decades and distance. Unlike most reunion stories that climax with a cliché happy ending, is a real-life drama. Journeying from the Vietnam War to Pulaski, Tennessee and back to Vietnam, tensely unfolds as cultural differences and the years of separation take their toll in a riveting film about longing and the personal legacy of war.
