Final Exposure follows JONAH MORGENSTERN (38), a disillusioned asylum officer with a passion for photography, who finds a dark outlet for his artistic expression after photographing a fatal accident. Unable to publish the image, he begins staging murders, capturing the deaths on camera. His first victim is TUGCE, a young asylum seeker, and he anonymously shares his work online under the alias “MArMOr1997.” As his fame grows, so does his belief that his art justifies his crimes.
Meanwhile, detectives DIRK MATAN (39) and EDITA ČERNÁ (28) investigate a series of murders that seem to be connected, but Jonah remains hidden behind his artistic success. As the detectives uncover disturbing links, Edita begins to suspect that Dirk may be hiding dark secrets from his past. The truth comes to light when Jonah’s childhood connection to Dirk, as “Moritz,” is revealed.
Jonah’s final victim is Ada, with whom he is having an affair. In a dramatic showdown, he lures Dirk and Ada to a ruin tied to their past, where past and present collide. As Jonah is finally captured, Katharina, his wife, kills him before he can be tried. The investigation leaves Dirk facing the unraveling of his career and the haunting memories of his youth.
