Bank clerk Aarno Harjus is dismissed from his job due to false criminal allegations, and at the same time his wife leaves him. With the help of his friend, Detective Inspector Erä, Harjus gets the opportunity to appear on the radio under the pseudonym Con Amore. Like many other women, nurse Rauni also becomes interested in the handsome singer.

The farce is set in Turku in the summer of 1940. Olavi Vuori, the son of a landowner, sets out to investigate shortages that have occurred in his father's lumberyard. At the site, he meets two bumbling friends, Sami and Santtu, who have unwittingly become involved in theft. Anni Koivu, an orphaned Karelian girl who looks after the pair's finances, falls in love with Olavi, much to the displeasure of their foreman, Haapala.
