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.

Adaptation of a popular comedy: When the country uncle he has been bilking comes to town to visit, a young student takes him to a boarding house full of exaggerated eccentric characters.

Landowner Klapproth would love to have his nephew Alfred show him the inside of an insane asylum and meet real lunatics, promising to financially support him in starting a business. Alfred's friend Ernst Kissling recommends that he show his uncle the Schöller Guesthouse, whose guests are quite eccentric. Landowner Klapproth, who truly believes the guests to be lunatics, is thoroughly amused.
