Redeye flight 29 from Los Angeles to Boston turns into a nightmare when ten passengers awaken to find the cabin eerily silent and the majority of their
fellow travelers vanished, leaving behind only personal belongings like dentures, hearing aids, and pacemakers. Among the survivors are Brian Engle, an off-duty airline pilot; Craig Toomey, a volatile, hallucinating businessman; and Nick Hopewell, a mysterious Brit with a dark past. Realizing the plane is flying on autopilot, Brian manages to land the craft at an empty, desolate Bangor International Airport.Upon arrival, the group discovers that reality feels "wrong." The air is stagnant, food tastes like cardboard, and the world lacks the vibrant energy of life. As they explore, they hear a terrifying, approaching sound—a low, grinding roar that intensifies as they wait. Brian deduces they have somehow slipped through a time rift into the immediate past, a place where the present has already been consumed. They are trapped in a decaying pocket of yesterday.Tensions escalate as Craig Toomey’s mental state collapses. Driven by childhood trauma and the voices of his abusive father, he becomes convinced that the mythical "Langoliers"—monsters his father warned him about—are coming to punish him for his failures. He descends into a murderous frenzy, stabbing the blind teenage girl, Dinah, who possesses psychic abilities. Dinah reveals the terrifying truth: the Langoliers are reality’s cleanup crew, biological entities that devour the past to make way for the future. They are fast approaching to consume the entire airport and everyone within it.The survivors scramble to refuel the plane while fending off the unhinged Toomey. In a desperate
race against time, they watch as the horizon literally disintegrates behind them, the landscape being shredded into nothingness by the approaching, spherical, tooth-filled horrors. Brian manages to pilot the plane back through the rift just as the creatures arrive, narrowly escaping the void. They return to the present, but the experience leaves them irrevocably changed. They realize that while they survived the monsters, they have witnessed the fragility of existence itself, returning to a world that feels hollow compared to the existential terror they narrowly escaped in the graveyard of time.
