Sixteen years ago Audrey Barreyre and her boyfriend break into a house on the Basque Corniche.
2003: Audrey comes to Elaura to apologize for her crisis during the bachelor party. But someone is lurking around the house where Elaura lives. 2019: In police custody, Patxi finally admits he was Maialen's boyfriend but claims to be innocent of her murder.
35-year-old Audrey, the only survivor of a mysterious serial killer who raged in the Biarritz region 16 years earlier, is brutally taken back to her past by a new crime: a 17-year-old girl is found murdered on the Basque coast. Nothing links this murder to the series of crimes committed in the early 2000s by the "Itsas Killer," but Audrey is certain that Itsas is back.
