It’s been three years since we last met Janne and Inari. Since then, they’ve had a daughter named Lumi. Janne and his friends experience a new adventure, this time on an autumn night. The boys go to a party but end up chasing Lumi who has disappeared. Meanwhile, Inari enjoys a girls-night-out and has an adventure of her own.
In the third instalment of the franchise, Janne embarks on an epic hike, a journey of self-discovery. His dreams of a tranquil retreat into nature are quickly shattered however, when Räihänen and Kämäräinen both decide to come along for the trip. Meanwhile Janne’s spouse Inari gets the chance to go back to work, but only if she can prove she’s “management material” and a real leader. Inari enters the Swamp Soccer tournament, where to her horror she finds out her ex Little Mikko is also competing.
