The evidence incriminates him, the details point to him—but something doesn't quite add up. In the city of Córdoba (Spain), Inspector Ava Martín faces a case that defies all logic: a series of murders that, disturbingly, seem to be linked to forensic expert Lucas Caronte. Methodical and relentless, Ava follows every lead, determined to unravel the truth behind the crimes. As the bodies pile up, Lucas shifts from being a mere witness to the central figure in the investigation. The evidence implicates him, the details point to him—but something doesn't quite add up. Is he being manipulated? A victim of obsession? Or is he truly the killer everyone is hunting? Every step of the investigation brings Ava and Lucas closer to a truth that could cost them everything. Amid suspicion, deception, and danger lurking around every corner, time is against them. Uncovering the real culprit isn't just a matter of justice—it's a matter of survival. A plot brimming with tension, unexpected twists, and a connection that goes beyond the professional, where the truth is as elusive as it is dangerous. How far would you go to uncover the truth?
