The Runway is inspired by the true story of a South American pilot who landed his plane near Mallow, in 1983. Against all odds, the people of the town came together to build a runway to get him home and briefly caught the imagination of the nation. It is the story of Paco, a young boy without a father who adopts the pilot and convinces the town to build a runway to get him home.

While Sandra opens up to a documentary film crew, flashbacks show her teenage son, Stephen, mysteriously kidnapping a toddler, and holding him captive. Eventually, the stories intersect to explain the abduction and the family's three-generation legacy of abuse in this mesmerizing psychological drama.
