“Tukkijoella” (Log River – 1928). Films of this genre gave the Finnish cinema and the viewing public one of its most popular characters – the lumberjack (tukkijatka, tukkipoika, tukkilainen) who at his most heroic hour becomes the log-roller or the shooter of rapids (koskenlaskija). The significance of this character in Finnish film is comparable to that of the Cowboy on American cinema. He is the pioneer, the wanderer, the adventurer. He negotiates the frontier, he is an embodiment of the conflict between wilderness and civilization.

The film starts at the countryside, where station master Viirimäki is spending his summer holiday. He has gotten into the holiday mood to the extent that he wakes up from his stupor at the very moment he should already be getting back to work. Unfortunately the last ship from the island where he has been vacationing has already sailed, but as luck would have it, local residents Himanen and Kehkonen promise to help him out. Things turn out differently, however, and the attempt to help starts out an adventure filled with misunderstandings and plot twists.
