In the 1800s, a stormy love relationship develops quickly between a young medical student and a woman believing herself to be the daughter of his scientist uncle, the student having never heard of her before their chance encounter and both unaware that she is the result of the scientist's illegal experiments with artificial insemination..

A series of stupid coincidences causes the young Munich painter Paul to convert his uncle's castle into a hotel for four weeks. But he can't complain: business is good and he has plenty of guests. For exmple, there's Theo Muller with his revue troupe. For reasons of "sound", Muller calls himself "Miller", which, of course, causes more confusion. His daughter, the beautiful Evelyn, is confused with Mabel Miller, who has come to the hotel on a mission for her filthy rich father ... namely, to estimate the worth of the castle.

An Austrian silent comedy crime film.

When a travelling troupe threatens to unleash a saucy Berlin revue on the provincial town of Emilsburg, the local Morality Society, a band of sanctimonious middle-aged men, stages a protest. Meanwhile, the reigning monarch is concerned that his son and heir is not living his life to the full. Ninon d’Hauteville, a showgirl and the revue’s star attraction, takes a job as piano teacher to the young prince after her engagement at the local theatre was brought to a premature end, a result of the Morality Society’s interference. It doesn’t take long for those hypocrites to get wind of this. While on the outside they appear to be concerned with running the immoral woman out of their town, behind closed doors they rank among the new piano teacher’s most ardent pupils. However, Ninon, out to right the wrong done against her, secretly keeps a “diary” of their visits, recording each encounter on film with a hidden camera.
