A French cultural research group arrives in Finland. From Helsinki, the group travels to Saimaa to participate in Midsummer rituals, where the summer night celebrations overwhelm the researchers.

Young photography model Susanna and her alienated teenage brother Veli spend the summer of 1969 travelling around Finland, mostly with another girl and her boyfriend. Sporting the latest fashions and trendy hairdos, they naïvely observe and criticise the modern consumer society, advertising, fancy boats and summer cottages, country dances, barbecues, and any other phenomena that were supposed to bother angry young intellectuals in those days. The plot and the political agenda are delivered with a cheerful, tongue-in-cheek mixture of documentary observations, fake TV commercials, fake interviews, philosophical voiceovers and titles, and a jazzy soundtrack by the progressive rock group Wigwam.

A man sets out to prove his right against a District Court in a small town. The locals are not willing to accept anything but their own truth of the matter.
