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.

Teenager Erik returns from Paris to Finland in a rowboat and is accosted by a gang of youths in the countryside. He walks to Helsinki, returns to his parents' home and his old high school filled with angry radical teens who, typically for the era, consider the teacher-imposed discipline as another form of capitalist imperialism. Almost reluctantly Erik drifts together with Annika, a girl from a wealthy family, and starts experimenting with sex and marijuana. In the same nonchalant manner Erik gets involved in demonstrations and school politics which escalate into a violent school strike leading to police intervention and heavy sanctions.
