On a Boeing 747 flight from London to New York, the wealthy architect Alan O'Neill travels with his wife Sheila O'Neill, and they have secretly tucked a druidic sacrificial altar into the baggage hold, a reckless act that will haunt every passenger. Aboard for the ill-fated journey are Paul Kovalik, an ex-priest, and Glenn Farlee, a man of vast means. The stage is set for a voyage that will soon descend into a nightmare.
Captain Ernie Slade tries to keep the jet on course as unseen forces take hold. The crew and passengers encounter a supernatural horror emerging from the baggage compartment—the ghosts of druids seeking vengeance for their uprooted resting place. The crisis worsens as gale-force winds push the aircraft back toward London, and the cabin grows icy as the spirits unleash terrifying visions and sudden displays of telekinesis. In a misguided attempt to appease the spirits, a doll is sacrificed, but the gesture only inflames their fury. Dr. Enkalla Dr. Enkalla is brought in to assess the phenomenon, while the ex-priest Kovalik tries to make sense of the haunting from the rear of the plane, hoping to understand what the druids want.
The truth emerges in a shuddering twist: the ghosts demand to be returned to their ancestral burial grounds, and they require a human sacrifice to complete the return. As the emergency door is blown open, Kovalik is sucked from the aircraft to his death, a sacrifice that appears to calm the spirits. With the threat neutralized, the remaining passengers cling to hope as the 747 finally descends and lands safely.

Alan and Sheila O'Neill, a wealthy couple, secretly tucked a druidic sacrificial altar into the baggage hold of the Boeing 747. This reckless act was committed greedily, as they apparently wanted the ancient artifact for themselves. However, the altar was a sacred object that belonged to druids, and removing it from its original site stirred the vengeance of druidic spirits whose remains had been disturbed.
The altar's placement in the baggage hold before departure sets the dark omen for the flight.
The ghostly force created by the druid spirits took control of the aircraft and pushed it back toward London. Gale-force winds battered the fuselage as the supernatural entity directed the plane to return to where the altar had been taken from. The spirits were driving the aircraft to bring them back to their original location.
The druids' vengeance would require returning to their ancestral grounds.
The interior began to freeze as the druidic spirits manifested their presence through extreme cold. The temperature dropped dramatically as the ghosts unleashed their power, causing breath to fog and surfaces to frost. This supernatural cold was one of the many terrifying phenomena the spirits used to torment the passengers and crew.
The chilling presence began shortly after takeoff when the spirits awakened.
In a misguided attempt to appease the spirits, a doll was offered as a sacrifice. However, the act backfired severely, the druids' ghosts found the offering insulting and inadequate. The act of offering a mere doll as a substitute for what they truly demanded inflamed their fury, making the spirits more powerful and increasing their violent attacks on the passengers.
The desperate attempt at appeasement occurred after other manifestations of the haunting had already begun.
The druid ghosts demanded two things: to be returned to their ancestral burial grounds and to receive a human sacrifice to complete the ritual. They sought vengeance for their uprooted resting place and required a life to appease their anger and complete the journey back to their homeland.
The spirits' demands were revealed late in the flight after Kovalik's investigation.
Kovalik was sucked from the aircraft through an emergency door that was blown open by the spirits. The ex-priest had been investigating the haunting and trying to understand what the spirits wanted. When the opportunity for a human sacrifice presented itself, the druids chose him, likely because his religious background as a former priest made him a spiritually significant offering, or simply because he was positioned near the emergency exit when the spirits acted.
Kovalik moved to the rear of the plane to investigate the spirits' demands, placing himself in the location where the sacrifice would occur.
The druid ghosts possessed supernatural powers that allowed them to manipulate physical objects. They unleashed horrific visions and used telekinesis to levitate or move desks, belongings, and other items throughout the cabin. This psychokinetic activity terrified passengers and created chaos, demonstrating the ancient spirits' ability to affect the physical world.
The telekinetic attacks began as part of the escalating haunting after takeoff.
After Kovalik was sucked from the aircraft to his death, the sacrifice appeared to satisfy the druid ghosts. Their demands having been met, the spirits relented and permitted the flight to continue toward London. With the supernatural threat neutralized, the remaining passengers and crew were able to complete the journey and land the 747 safely on the London runway.
The ghosts had explicitly stated they required a human sacrifice to complete their return.
The druid spirits were angry because their sacred altar had been removed from its rightful place, their ancestral burial grounds. The O'Neills' act of smuggling the druidic altar overseas profaned the sacred site and disturbed the remains of the ancient druids. This violation triggered the spirits' need for vengeance against those responsible for the desecration.
The altar was secretly placed in the baggage hold before departure, sowing the seeds of the druids' revenge.
The druid ghosts demonstrated powerful supernatural abilities that extended beyond the cabin. They were able to push the aircraft back toward London using what appeared to be telekinetic force, creating gale-force winds that battered the plane. This allowed them to direct the aircraft toward their desired destination, the location where the altar had been taken from.
The supernatural awakening occurred shortly after takeoff, indicating the spirits' power over the aircraft.
