On a rugged trek through the Scottish Highlands, a tight-knit group of Glasgow teenagers stumbles upon an abandoned baby hidden in the ruins of a remote castle. As they struggle to get the infant to safety, a shadowy, wolf-like beast emerges from the darkness, stalking them relentlessly and picking them off one by one. The mood tightens with every rustle in the night, and the sense of isolation on the moor grows stronger as the danger closes in.
Realizing they cannot stay on the open moors where the creature can easily strike, the group retreats to the castle—the monster’s lair. Inside the ancient stone walls, fear fights with resolve as they try to improvise a plan to survive the night. Among the teens, David and Mark stand out as part of the cohort working with their peers to keep the infant safe. The tension rises as the beast roams the corridors, and a harsh realization settles in: whoever is left outside will be hunted down.
In a desperate bid to turn the tables, Kelly Ann [link: /actor/samantha-shields] lures the creature up a flight of stairs, drawing its attention away from the others. The plan is simple but brutal: the group pushes a heavy stone down onto the beast and then closes in with spears. The fear and adrenaline fuse into a coordinated effort, and for a moment it seems the monster has been defeated. Yet the danger isn’t over—the castle’s interior holds another threat, and soon a second beast enters the scene, tearing into the group and claiming another life.
Only Lee and Kelly Ann remain standing after the carnage, racing to put distance between themselves and the menacing forces outside. The creature’s mate appears to mourn the loss with anguished groans, but its grief quickly morphs into pursuit, and the chase continues across the stone floors and into the dark night beyond the castle walls. The two survivors are forced to rely on each other as they flee deeper into the countryside, with the relentless threat looming behind them and the reality of what they’re facing becoming clearer by the moment.
Seeking a safer haven, the pair eventually reaches the hotel where they were supposed to meet their guardian, Father Steve. Inside, the tension peaks as they navigate to a bedroom where the infant is cared for. Kelly Ann hovers over the baby to feed him, unaware that danger lurks just beyond the door. The Monster materializes, slaying the hotel’s owner and driving [Father Steve] into the room where Kelly Ann stands. In a brutal moment of horror, the mother monster discovers a feeding pairing—she is feeding her pup—before turning on the guardian and ending his presence. The grim truth becomes clear: the baby is the werewolves’ child, and Kelly Ann’s earlier act of nursing the infant left her infected by the biting memory of that moment.
As the credits roll, a quiet, unnerving image lingers: two beasts walk through a field back toward the castle, their young trotting nearby, a haunting reminder of the bloodline that now links to the infant at the center of this nightmare.
