Nerea Garcia is going through a rough patch. Four years have passed since she was kicked out of the police and she’s been living an isolated life, hidden away in her house in Bilbao. But when the body of a woman turns up, apparently murdered in some kind of ritual killing, her old boss gets in touch to ask for help with the investigation. What Nerea doesn’t suspect is that the ghosts of her past and present will force her to return to the dark, dirty streets of the city, where nothing and no one is what it seems.
