Lisa initiates contact with Mark, but he proves to be his usual prickly self and then ends up taking things a little too far.

Lisa, a physiotherapist, starts her new job in an institution for people with learning disabilities. She meets Mark, who is actually just being kept there temporarily and who initially reacts to her in a dismissive, almost aggressive way.

After spending years in prison, Mr. Lehmann is up for retrial. Andrea's husband is acting as his lawyer now – will there be a new outcome?

Andrea Bredow visits Mr. Lehmann in prison and says that she believes him. Now, things are turning serious for Judith Lorenz, who is facing a retrial.

After doing a little digging, Andrea is convinced that Judith has told her nothing but lies throughout their whole friendship. And so she decides it's time to confront her.

A year and a half after Judith's resignation and the end of their friendship, Andrea receives an invitation to Judith's birthday party. Perplexed by a strange coincidence she notices, she decides to attend and see what she can find out.

Ms. Lorenz asks to visit Mr. Lehmann in prison, where he gives her a letter to read, as his therapist recommended. In the letter, he begs her to tell the truth and clear his name so that his daughter won't suffer so much.

Andrea learns that Judith is in the hospital and goes to visit her. Andrea can't imagine that Judith has been poisoned as she claims, and it does seem that a lot of bad things keep happening to her.

Judith is quite dismissive of Andrea's husband's attempt to express sympathy, and then makes an impossible request of Andrea. Meanwhile, Mr. Lehmann loses control in prison.

Andrea begins to question Judith's new memories of the incident, and asks her husband about it. When she goes to a bar, she finds Judith's behavior quite worrying.

Testimonies from Judith Lorenz and Volker Lehmann regarding their encounter in the storage room are heard in court, and the verdict is revealed.

As the trial approaches, Judith spends more and more time with Andrea, even visiting the zoo with her family. During this excursion, Judith mentions that she once had a daughter.

After things become unpleasant for him at home, Mr. Lehmann makes the bad decision of going to Ms. Lorenz's apartment to confront her. His lawyer is concerned that this makes him look quite bad in court, especially now that Ms. Schmidt, his main ally at work, has passed away and can't defend his character.

Ms. Gonzor and Mr. Lehmann discuss the complaint that Ms. Lorenz has filed against him, and Ms. Gonzor tells Mr. Lehmann that he will need to stay home while the investigation is taking place. However, he does not want to accept this…

The police confront Mr. Lehmann with Mrs. Lorenz's accusation. Mr. Lehmann reacts arrogantly, but privately, he’s worried.
