Big farmer Germund is planning a wedding for his daughter Marit with the local farmer boy, Mats. Everything seems to be going according to plan. But one day Marit meet with fiddler Jon, a bastard who enchants youth with his violin. Everything is just like the old reliable drawings. Folkmusic, barn dance photos, fights, rough fists groping the heroines bosoms, grand environmental images, the fresh fragrant of scouring-soap and lots of rustic atmosphere. In Mai Zetterling as farmer's daughter the director Gustaf Edgren has found the personified Swedish summer night, as both the seductive twilight and the sober dawn in her blond revelation. And Alf Kjellin as Jon in dark curly wig gives a solid interpretation of the fiddlers temperament and the abrupt shifts between melancholy and frivolity. Both Zetterling and Kjellin later moved on to become well known international film directors. "Driver dagg faller regn" was the first Swedish film to gross more than 1,5 million Swedish krona. It took more than ten years to break that box office record. Ingmar Bergmans "Smultronstället" (Wild strawberries) did in 1957.
