In this high-spirited and highly successful comedy with a very strong cast and quite a few hit songs, three younger men each has to step up to the challenge and overcome the local and rather maniacal patriarch Mikkelsen (Johannes Meyer). Vilhelm (Paul Rohde) is to take over the patriarch's business and marry Mikkelsen's daughter Anna (Gerda Sprehn). Kristian (Hans W. Petersen) is Mikkelsen's unknown son about to win the national bicycle championship and to marry Mikkelsen's lodger Lotte (Beatrice Bonnesen). Nummesen (Chr. Arhoff) is Mikkelsen's wit-full friend about to help everybody out and eventually to marry Mikkelsen's housemaid and former mistress Rasmine (Helga Frier). Rare for it's days, the movie is partly filmed outside the film studios in iconic localities around nostalgic Copenhagen: Bellevue Beach, Dyrehavsbakken entertainment park and Ordrup bicycle racing track.
