Sweden in 1975: a shared house full of long-haired, politically aware, sexually progressive young people who want to live a self-determined and collectivist life at the same time. They eat a vegetarian diet, drink lots of red wine, forbid the kids coca-cola and differentiate between social democratic and socialist ... One day, the good-natured Göran's sister and her children flee their middle-class marriage for the shared flat - a new element in the daily hullabaloo.
