When a young boy disappears in Norway’s remote, wolf-inhabited forests, biologist Emma Salomonsen returns to her estranged father’s town of Østbygda to check on him. Her father, Marius Stenhammar, a renowned wolf researcher, has been behaving erratically, and the community is quick to blame the wolves for the missing child. But when Emma discovers the boy’s bloodied jacket, covered in wolf hair, inside Marius’ home, suspicion turns toward him instead. Before she can get answers, Marius vanishes without a trace.

Determined to uncover the truth, Emma joins forces with journalist Naim Karimi, delving into a tangled web of small-town secrets, paranoia, and long-buried family trauma. As tensions escalate and the wolves become a target, Emma must separate fact from fear before the real threat closes in.

With gripping storytelling and a haunting atmosphere, Fenris is a tense Nordic thriller exploring the fragile balance between humans and nature, and the dangers lurking in the wilderness.
