Special investigator Alexander Haller rushes to the emergency room: his former partner and friend Martin Scherf, recently released from prison for the murder of his girlfriend, is lying dead after being shot. With his last strength, he asks for protection of an unknown woman who Haller has yet to find. In order to clarify what was the ex-policeman's undoing, Haller delves into the old case that he had given up due to bias. From the then head of investigation, Bollinger, he learns that he has doubts about Martin's confession. What really happened back then? A lead leads to Sophia Wallenberg's coffee house chain and its manager. Plagued by feelings of guilt for having let his friend down, Haller falls out with his confidant Niko. Without his "eye," the blind special investigator's reliable instincts no longer work flawlessly. When Haller gets into danger, he needs his friend's help.
