During a family gathering, a celebration for their father's 60th birthday, the eldest son presents a speech that reveals a shocking secret to everyone.

It is the adult Gustav Adolf, who tells the story of the momentous day when he as a little boy with his father and mother and the whole staircase, went to the beach to enjoy the pleasures of bathing. We are in 1930s working-class neighborhood in Copenhagen. In a backyard apartment, we meet the little working-up of small Gustav Adolf (Benjamin Rothenborg Vibe) who has great respect for his father, Axel (Erik Clausen). Father has a very lively gab and is always ready to tell a story from her exciting life - often from the time he was on the big Argentine pampas.
