The renowned physician Prof. Markus Gärtner becomes the new head of the planned cardiac research center. To make it as easy as possible for the specialist to settle into his new place of residence, clinic director Prof. Weissing commissions a relocation agency to take care of his wishes and concerns from now on. Although she sends her best employee, Lina Baumann, she seems to fail because of the gruff, humorless doctor. Every apartment she chooses displeases the single doctor. He is also annoyed by all the joint activities. He only has work on his mind and would like to start immediately.

Claire and David have been happily married for years, but there seems to be a curse on their marriage. They have been trying to have a child for a long time, but unfortunately without success. When David dies unexpectedly, Claire's life is thrown into complete chaos. But as she tries to come to terms with the loss, she suddenly discovers dark secrets that cast her husband in a completely new light: the respected aid worker was apparently involved in dirty business in Africa. And then for years he has also kept it from Claire that he has been having regular sex with the call girl Sabina. Suddenly more and more strange things are happening and Claire suddenly feels persecuted. Could David have been murdered? If so, who has something to cover up? And what did David's assistant Michael know? For Claire's psychiatrist and David's confidant Hagedorn, these are just delusions. But who can the widow trust now?
