Elmeri Vara from the General Stabilization Party, Selma Vuorinen from the Free Enlightenment Party, and Irja Solanen from the Independent Women's Party are competing for seats in parliament. When young Pertti and his classmates start a campaign with caricatures against Vara and Vuorinen, whom they consider unfit, Principal Reino has to decide whether to support the parliamentary candidates or his students, and how he feels about the candidacy of his beloved Irja.
