A child who is the subject of a custody dispute flees from the social welfare authority from Tyräaho to Helsinki with Pekko. In the capital, the friends are helped by Pipsa, Pekko's crush, who joins them on a runaway trip. The press and the people of Tyräaho follow the trio's antics unflinchingly.
The film tells the story of two very popular Finnish singer/songwriters: Tapio Rautavaara and Repe Helismaa, who worked together until their relationship got frictious for a long time. The film covers the years from 1949 to 1965. Since the film is based on real-life persons it also tells much about the change in Finland during those years and of course much about Finnish popular music.
