After losing her sight at twelve years old, Blanca finds herself one step away from realizing her life's dream: working in the police force. But once she arrives at the police station for an internship, she comes up against everyone's distrust. Thanks to the skills that she has developed over the years, however, and the help of her dog Linneo, Blanca turns out to be a detective with a different and effective "look". Taken from Patrizia Rinaldi's novels, it is the first television series in the world shot in holophony, a special sound recording technique that allows the viewer to be in the protagonist's place: to feel how she feels and reconstruct the world.
