Olli Suominen goes through the usual troubles of a teenager. After being in the war he is trying to find his place in the society. And the relations with his family is in turmoil.

An artist bases a painting for a revealing lingerie ad on a photo of a girl he had found torn from a magazine, not knowing that the girl is in fact the daughter of the Finnish minister of finance. A scandal is about to erupt, and the artist is given 48 hours to find a strikingly similar-looking female model who could serve as his alibi. The minister's daughter decides to fool the artist by pretending to be a lowly girl of the streets, whom the artist then recruits as his "model".
