En tidlig sommermorgen, på et vandrerhjem, finder man blandt gæsterne to unge piger. Den lille kontordame Ilse (Lis Smed) og den juridiske studine Ruth (Inger Stender). Af deres samtale forstår man, at Ilse har et meget borgerligt livssyn. Ved et tilfælde støder de to piger på en af Ruths studenterkammerater, Pontus Berthelsen (Mogens Wieth). Han tilbringer sommerferien i en lille fiskerhytte, som hans ældre og mere velbeslåede bror har lejet.

The action begins one early summer morning in a hostel, where we see, among others, two young girls, a law student, Ruth, and a small office lady, Ilse. From their conversation, we understand that Ilse has a very bourgeois outlook on life. By chance, these two girls come across one of Ruth's fellow students, Pontus Berthelsen, who is spending the summer holidays in a fisherman's cabin. Ilse, who has little world experience, quickly takes an interest in Pontus, who possesses a lot of innate charm. Pontus does his best to conquer Ilse, but her bourgeois attitude means - at first - that she does not fall for his rather deft approaches.
