The film follows Finnish army machine gun company in Continuation War against Soviet Union, 1941–1944. Based on Väinö Linna's best selling novel Tuntematon Sotilas (The Unknown Soldier) and the novel's uncensored version, Sotaromaani (A War Novel).

Touko Laaksonen, a decorated officer, returns home after a harrowing and heroic experience serving his country in World War II, but life in Finland during peacetime proves equally distressing. He finds peace-time Helsinki rampant with persecution of the homosexual and men around him even being pressured to marry women and have children. Touko finds refuge in his liberating art, specialising in homoerotic drawings of muscular men, free of inhibitions. His work – made famous by his signature ‘Tom of Finland’ – became the emblem of a generation of men and fanned the flames of a gay revolution.
