We follow the rootless Sinsen gang in good times and bad. A life that consists of rock concerts, hut trips, amusement park visits and car thefts. The year is 1958, when the Americans launched the Explorer and the Russians Sputnik III. However, these events do not interest the youthful persons in this film, the members of the "Sinsen gang". For them, it is far more important to know which rock hits are on top on Top Twenty on Radio Luxembourg, and to have seen the latest film with Elvis. The most important is to be accepted by the gang, to be loyal to your pals, and for a very few to be prepared for school

A group of young people have finally fulfilled their dreams from school days – they have got jobs and "freedom." But freedom brings with it new and heavier responsibilities. They decide to realize one last dream and breathe new life into their old school band – moving to the countryside and making a living from gigs. And it's a success! But there's a flip side to the coin: the long-awaited freedom isn't theirs – they're being controlled from outside.
