A violin student studying in Switzerland returns home to Sweden to visit his mother. During the summer vacation, his mother reveals the boy's late father fiddled around with more than the violin as the classical virtuoso engaged in numerous extramarital affairs. His sister is revealed to be only his half-sister as they both have different mothers. His sister longs to have sex and casts her lustful eyes towards her dear brother. He spends the night with three naked women who each take turns relating the sordid details of their first sexual experiences. Even Swedish censors had an initial reluctance to allow the film to be released because of the graphic content of sex and nudity. They finally relented, allowing those 15 and older to see the feature. ~ Dan Pavlides, All Movie Guide
