Do you know what the Crime Club is? Fifteen-year-old Daniel has to recover after a brutal accident that took his father's life and left his mother in a coma, lying in a hospital bed. While trying to reconstruct the last moments of the event, he stumbles across a strange robbery in his parents' psychiatric surgery. When the police fail to understand, Daniel starts to investigate the matter with the help of his friends Sara, Jonatán and Laura and discovers that a dark plot of old secrets surrounds the mystery of his parents' life and, worse still, he begins to suspect that the accident that cut short their lives was not in fact an accident... From this moment on, he makes contact with a secret organisation that will do everything possible, despite all of Daniel's efforts and skill, to remain in the shadows and keep hiding its precious secrets from the world...
