Rolf is pulled out of his cell and taken to Police Commissioner Astrid Oxvig. She has heard about the DNA match between the Minna case and the murder in France, and wants Rolf to take over the case together with a French investigator, Claire Bobain (35), who Rolf is sent to pick up at the airport; with the Minna files still mysteriously AWOL, he is one of the few people who can provide context for the French investigation, and he is not to disappoint their European colleagues at a time when cross-border cooperation with Denmark is fraught. This new development reawakens Rolf’s hope of finding another perpetrator than Minna’s father – one with possible knowledge of his daughter’s disappearance. 
When Claire arrives, she together with Rolf and Neel reopens the Minna case in order to investigate the French murder. They talk to Minna’s mother again and notice her mentioning the name Sabina and some phone calls from her to Minna’s mother. Neel gets a list of numbers calling the mother, and there is a Polish number among them. The new lead make Claire and Rolf agree that they must go to Poland once again, to review the case with the Polish Police. 
The evening before they leave, Thybo and his wife Eva invite Rolf and Maria over for dinner. Rolf is drawn to Maria once again and happily accepts her offer to look for an apartment for him in Copenhagen. 
In Poland, Claire and Rolf learn that the witness, who Rolf never got to talk to five years earlier, has disappeared. Furthermore, their local liaison officer Karol knows nothing about the only pieces of evidence that support the accusation of Zaid going to Poland with Minna: a sweatshirt with his DNA and a drawing with her DNA, which were apparently found in a motel nearby the ferry. Rolf and Claire call Neel to get her to ask Hviid who found the pieces of evidence back then? Unfortunately, it turns out there was a gap from Rolf leaving the case to Hviid taking over, and in between, it was handled by Frode Markmand, Thybo’s predecessor. Neel contacts Frode, who now sadly suffers from dementia and can’t tell her anything. But his caretaker reveals that just the day before Neel’s visit, a man came to talk to Frode about Minna. Neel is spurred, can this be a coincidence? On her way out, Frode hands her a stack of papers. Between them lies a creased file on the Minna case. On the back is written a name: Sabina, and an address. Neel hurries out. 
Meanwhile, Rolf wants Karol to check the cars on the ferry on the day of Minna’s abduction. But as there is nothing there, he asks to check the cars on another date – the day of Andrea’s disappearing. It becomes clear that Rolf has let himself be blinded by his longing for answers to his own personal tragedy, and is mixing the two cases. But it turns out that there was a stolen car onboard that very day, which was later dumped into a river. A picture from the car indicates there had been a baby, swept in a vest with a symbol of a glowing cross and two hands, in the car before it was dumped. Rolf is speechless. Could this have been Andrea? 
Just then Neel calls. She has the address for Sabina, and the phone number they found earlier matches it. Claire and Karol pull Rolf out of his bubble. She must be the witness, and they need to go there immediately!

In parallel, we continue to follow the strand of Julita, which we find attending the funeral of Aron, still carrying his child. She learns that a lot of Polish girls are giving up their babies to a group of nuns, who make sure the babies get good homes, as the girls simply can't afford or manage to raise the children. Julita is shocked: she is determined to keep the child and raise it by herself despite the pressures of her and of Aron’s families. 
But one day she breaks down in pain and is immediately hospitalized. Julita has pre-eclampsia and cannot be physically active during her pregnancy. She can’t afford not to work and therefore seeks help from the Catholic charity organization Mandorla. The organization’s symbol is a glowing cross and two hands holding one another… just like on the evidence Rolf has just seen. Julita is relieved to stay at Mandorla and doesn't feel suspicious, though a few ominous details tell us perhaps she should.
