Documentary about the artist Pierre Isacsson, whose song "Då går jag ner i min källare" became one of the biggest Swedish hits of the 1970s. The vast majority of people recognize the characteristic whistling melody - but few know who was behind the super hit. This is the story of an artist who came to hate his most successful song and whose career ended painfully when it was time for a comeback. But it is also the story of a son who gets to know his long-dead father via some old cassette tapes.
