In a small Danish village, a group of elderly residents is shaken by a series of strange events that seem to be connected to an ancient Nordic myth. The story follows Einar, a retired fisherman who, after a storm, discovers a mysterious object on the shore: a stone with inscriptions that recount the legend of a mythical creature that awakens in the harshest winter. As the community grows colder with the arrival of winter, disappearances begin to occur, sending chills down the spines of the villagers.
Tension escalates when Einar, along with a group of friends, decides to investigate the legend, believing that the so-called "Beast of Winter" may be the culprit. As they unravel the secrets of the past, they find themselves enveloped in an atmosphere of paranoia and fear that begins to fracture their friendship. What seemed like a simple tale turns into a desperate struggle for survival when they realize that the line between reality and myth is thinner than they thought.
With a focus on the psychology of its characters and a backdrop of Nordic folklore, this film blends horror and human drama, as Einar and his friends confront not only the creature but also their own fears and traumas. The story culminates in a chilling climax that will challenge their understanding of life, death, and madness.
