Sami, a deaf woman, survives alone in a suburban wasteland stalked by a terrifying presence beneath high-tension power lines. Her only warning of its approach is a faint hum detected by her cochlear implant. Clinging to the hope that her missing family will return, she refuses to leave her fortified home, even as the military prepares to destroy the entire area. When two mysterious intruders arrive claiming they can destroy the creature using a bomb “fueled by Hell,” Sami’s world begins to unravel. Childhood trauma resurfaces, memories shift, and her grip on reality weakens. In a climactic confrontation, Sami deploys the bomb and wakes in a hospital to a reunion with her long-lost family. But as buried truths surface, she realizes the reunion isn’t real.

In a small town, high-school dean Alana and her vivacious teenage daughter Samantha plan a holiday concert to save the school with the help of the new maintenance man, Army veteran Johnny, and his quiet son Max. But when a car accident lands Sam in a life-threatening condition, Alana turns to Johnny for support, and Max makes a desperate decision that will forever bond their families together. All four must question their values about sacrifice, family, and love - and what it means to be thankful for another Christmas.
