It tells story about Tommy, the twelve-year-old boy, who tries to help a lynx named Leevi to survive in the wilderness.

It is assumed that he climbed up the mesh fence and fell on a sharp stone, which resulted in the death of the animal.

[5] 12-year-old Tommy (Konsta Hietanen) moves to Lapland with his zoologist father Olli Oksa (Antti Virmavirta).

Father's job is to return the Leevi lynx back to nature, but reindeer herders don't like a beast that threatens their property.

The young conservationist Oula (Jussi Puhakka) calls Tom out of the forest and prevents him from feeding the lynx, because then the animal won't learn to hunt on its own.

Leevi gets trapped in a cage equipped with a radio signal at some point, but Tommy tries to save it from trouble.

After this, Herman Haapala (Jarmo Mäkinen), known as a local animal stuffer, plans to go hunting for lynx.

When he approaches the lynx with a gun, Leevi attacks at the last moment to break free from the trap and both fall down into the ravine.

Tommy tries to drag the unaware Haapala out of the forest on a sled, but the slow progress leads to the darkening of the night and increasing frost.

After recovering, Tommy meets Jouko, who apologizes for killing the lynx protected by the boy's mother.
