Hiltrud Janssen soon achieves what only a few people in her life are able to do: she celebrates her 100th birthday. It’s just a shame that she fell out with her younger sister Betty many years ago. Back then, Betty worked as a housekeeper for the influential CDU politician Heinrich Verhoeven and had an affair with him. Verhoeven was accused of adultery, but Betty was able to convince her sister Hiltrud to make a false statement. Verhoeven was acquitted and Hiltrud never spoke to Betty again. Hiltrud and Betty’s sister Martha, now 98 years old, thought the 100th birthday was the perfect occasion to reconcile the estranged sisters and arranged a meeting.
