French milliner Yvette has a small fashion salon in Düsseldorf. The young gentlemen of society fall at her feet, but she is not accepted into their circles. That's why her former lover Maurice Daurignac manages to persuade her to pull off a big coup to get revenge on "high society". She pretends to be the heiress to ten million gold francs. A notary arrives from Paris accompanied by two supposed policemen and delivers the alleged money in a sealed parcel to the Bleichstetter bank in Düsseldorf, where it remains until the end of the inheritance process. The case drags on, and in the meantime the two are living large. When the bombshell bursts, Yvette has the young lawyer Dr. Hellmer to thank for the fact that she cannot be thrown to the angry citizens.
