Hannah is a clever women. She is driven by pain and vengeance and doesn't shy away from conspiracies. She's been dealt a tough hand: Her husband Michael commits suicide and their son Jonas gets sent to a psychiatric inpatient facility shortly after.
Hannah works as a masseuse in town, including at the power plant. She has a cool relationship with her mother-in-law Ines Kahnwald.
An ill-fated affair
Hannah falls in love with Ulrich Nielsen as a teenager, but Ulrich takes no notice – he's already with Katharina. When Hannah secretly watches them having sex, she devises a plan. She tells policeman Egon Tiedemann that Ulrich raped Katharina. The lie isn't without its consequences: Ulrich is arrested and Hannah spreads the rumor that Regina Tiedemann was the one to make the accusation.
Thirty-three years later, Hannah and now-married Ulrich end up having a secret affair. When the fling ends, Hannah is absolutely furious. Katharina finds out about the affair and confronts Hannah about it. Hannah lies again, claiming she was the one to end it and that Ulrich wants to leave his wife.
Hannah has been keeping a secret. As a teen, she witnesses Aleksander Tiedemann burying a plastic bag in the forest. She recovers the bag and finds a gun and passport with his real name: Boris Niewald. Thirty-three years later, Hannah uses this information to blackmail Aleksander, asking him to wield his power as director of the nuclear power plant to ruin Ulrich's life.
