When a young girl is found dead in the Basque Country, a lawyer feels driven to find out more, as she links the crime to an assault on her many years ago.
Audrey suspects that her would-be killer is back, but she must proceed carefully. The police are sceptical of any suggestions she makes. She gets a shock when she sees detective Pauline's father.
Pauline and Joseph are willing to work together to track down the killer. A reporter reveals more information about her past than Audrey is prepared for.
There's another death, and all bets are off about the murderer's identity. Pauline is rushed to hospital and Joseph urges Audrey to go back to her family.
In the past, Audrey had interfered with Joseph's life. Currently, he is the only one who believes that she's telling her truth. Joseph is getting closer to the truth about Itsas.
