After clues have pointed to Poland, Rolf and Claire leave and find a witness who is in possession of a video.

Claire is worried because Rolf seems more concerned with his daughter's case than with the current murder case.

In Paris, the two men, Grégoire and Fabien, are brought to trial in connection with the killing of Victoria, and they confess to having paid her to be the surrogate mother of their baby. Several tracks lead Rolf and Claire back to Poland.
