Following his violent encounter with the mercenaries, Aatami discovers they were hired by an international treasure hunter, Viktor Rudenko. Rudenko is after a fabled treasure hidden during World War II — a hoard of gold even more valuable than what Aatami recovered. A map to the treasure has been uncovered, and Aatami’s reputation as the man who can’t be killed makes him the perfect obstacle for Rudenko to eliminate.

Aatami reluctantly sets off to retrieve the treasure, not out of greed but to ensure it doesn’t fall into the wrong hands. He teams up with Helena, a resourceful resistance fighter with a vendetta against Rudenko.

The journey takes them across perilous terrain: dense forests, abandoned bunkers, and icy rivers. They face relentless assaults from Rudenko’s men, including a former SS officer who survived Aatami’s wrath in the first film and now seeks revenge.

Aatami and Helena’s bond grows as they share stories of loss and survival. Helena, inspired by Aatami’s resilience, begins to understand the true meaning of “sisu.”

The climax unfolds in a massive underground war vault, where the treasure is hidden. Traps, ambushes, and brutal hand-to-hand combat ensue. Aatami faces Rudenko in a ferocious battle, showcasing his legendary toughness and ingenuity. Despite overwhelming odds, Aatami’s indomitable spirit prevails.

In the end, Aatami ensures the treasure is destroyed, preventing it from being used to fuel further conflict. He returns to his cabin, battered but unbroken, ready to rebuild his quiet life once more.

Aatami sits by a roaring fire, the faint echo of past battles in his mind. As the camera pans out, a group of children approaches his cabin, curious about the “Immortal” man. Aatami smiles faintly, a rare glimpse of his humanity, as he tells them a story of courage and resilience.
