It features a number of songs performed by leading German Schlager music singers of the era.

On her 21st birthday Gerda, a young student, is summoned by a solicitor who informs her that she has inherited one million Marks from a deceased aunt and will be presented with a suitcase later that day.

When the suitcase is delivered to her apartment, Gerda and her friends Morits, Rudi and Karin are disappointed to find it does not contain the money, but a heap of old fashioned identical granny dresses, all looking the same.

They include an arrogant film star, a bad tempered mid aged woman with a dog, a lady who works at the hotel and the slightly gawky Bruno.

The chase is on, partially in disguise, which causes lots of errors and confusion, to locate and to check every single dress without being too obvious.
