Blanca has been blind since childhood — but what others see as a weakness, she wields as her deadliest strength: decoding crime through sound as a brilliant police audio analyst. In the second season, a ruthless serial bomber, both dangerous and defiant, is terrorizing the city and taunting the police. Blanca and her team must stop him before he strikes again, but as the investigation unfolds, she is forced to confront long-buried ghosts from her past — this time tied to the mystery of her mother.
