A real event anchors the narrative: the Parot doctrine was abolished in 2013, and that moment becomes the springboard for the fictional drama that unfolds. The series, which aired on Thursdays at 10:40, introduces a tough mystery about a detective who must track down a killer targeting prisoners released early on controversial judicial grounds. The killer acts as a vigilante, arguing that justice has to be more than a formality when the system itself has let dangerous offenders slip through the cracks. The central theme probes whether the scales of justice are truly balanced, especially given the protagonist’s family background in law. As the plot threads through this police-centric thriller, familiar names surface: Blanca Portillo portrays the protagonist’s mother, a psychologist who adds perspective to the complex family dynamics; Ivan Massagué features as one of the assailants connected to the case; and Javier Albañal appears as a police colleague who plays a critical role in the inquiry. The show lands on Amazon Prime Video, launching a year after its initial release, and weaves together professional duty with personal turmoil to create a tense, morally intricate story.
