Raili moves away from her mean aunts. The young woman enjoys her independent life, but debt, a deceitful boyfriend, and getting fired from her office job get her into trouble. However, Raili's uncle Salomoni and his wife Salli support their relative. Olli, a lawyer, also wants to help Raili, who has fallen victim to blackmail.

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".
