It is really a boring Swedish drama comedy about a loveless marriage where love is luckily still found within the family as the man in the house have a love affair with his own niece in what almost feels like an "accepted incest story". A stage show with a sexy dancer halfway in the film is why this movie has become famous, but most of the film feel like an theater play.
Neither erotic, comical, nor amusing, I can only surmise that this relic has survived the test of time due to its (limited) prurient value. A sexy dance and an aeroplane scene are not sufficient to make this an interesting film. There are much better examples of Scandinavian silent cinema! For Instance: THE PHANTOM CARRIAGE, HAXAN, and others. This film is a bore, but the 2006 score added for the film is quite good.
