Liebling, wir haben geerbt! (2007)

Housewife Hannah Held, nee Liebetanz, has been fidelity to her dentist Martin for 27 years, in good times and bad. But when she happens to find out that he is cheating on her with his young practice assistant Annika, the oven is out for her: "I'm getting a divorce!" Explains Hannah angrily. With this determined exclamation, however, she causes a scandal at the annual foundation festival of her great-aunt Kthe. Shortly before, the wealthy old lady had publicly handed over the imposing family villa to Hannah, including the management of the multi-million dollar love dance foundation. Now Hannah is in a quandary, because she knows only too well that the tradition-conscious great-aunt values stable marriages above all else: she will never entrust the expensive family inheritance to a divorcee. Torn between the just outrage about her husband's infidelity and the responsibility to the family, Hannah plays down her appearance at the party as a skipping act and moves into the villa with her future ex-husband. The separation of table and bed is, however, precisely regulated by contract - an invisible wall divides the venerable property into two halves and on the outside the two mimick the happily married couple. They succeed so well that even their two adult children Lola and Paul can no longer see through it. And soon Hannah and Martin themselves no longer know where love ends and lies begin. Little did they suspect that the clever and forward-looking heir-aunt has long since caught up with them.
