The evidence is overwhelming, and the case seems clear. Sorjonen has only one mission: to prove his daughter's innocence. Sorjonen is a brilliant investigator, but murder and mayhem haunt him even in his sleep. Until now, it was about the fate of others. That is no longer the case: His own daughter is embroiled in a bizarre murder case, and all evidence points in her direction. Sorjonen's hands are tied. Ultimately, he begins to investigate on his own, alongside his colleague Lena, a former Russian FSB agent. The closer he gets to the true culprit, the more he puts himself in danger. Because the perpetrator wants only one thing.
