Two musicians, Hans and Peter, are out of work. They make regular visits to the booking agent, but there's no work. After several false starts, they are desperate, and when they hear that an all-woman band, the Alpine Violets, have been let down and are desperate for two female musicians, they know that fate is knocking for them. When they hear that the band is going to a luxury Alpine hotel to record a gramophone record, they can't wait to get on board. They enlist the help of a friendly makeup artiste and practise their girly body language. After a street test they are sure they pass, so it's back to the agency to volunteer. They pass a quick audition, so it's down to the station for the night train to Ingolstadt, with the rest of the band. They get introduced to all the other girls, who are already in their pyjamas in their sleeping berths. After a lot of giggling and innuendo, fortunately they are in their own compartment for the night.
