The film is based on Finn Bø's play Konge for en natt (King for One Night),[2] which had been staged at the New Theater.

Carsten Winger stars as a young unknown man named Hansen that ends up in a boarding house in the western part of Oslo on the same day that another man named Hansen (Axel Kielland), a real charmer, is expected.

A lot of strange things happen at this boarding house, including a fire.

However, the misunderstanding is cleared up, and the real Hansen is caught by the long arm of the law.

Winger is released and becomes engaged to the model Miss Nord (Liv Bredal).
