S1, E6: George is in a coma after an attempted murder. The station mobilises to support Charlie and find the killer. While Chris investigates a burglary gone wrong, Billon tries to keep Charlie away by assigning her to a parcel theft investigation. But this is to misunderstand Charlie, who, with Samy's help, is determined to get to the bottom of the attempted murder of her grandfather, behind the backs of the rest of the brigade. She soon discovers that the various clues incriminate her. A race against time begins to stay one step ahead of Chris's investigation, but doubt gradually creeps in: could Charlie really have attacked George? It's thanks to the trust and support of Samy, who doesn't believe for a second in her guilt, that Charlie manages to foil the trap that has been set for her. She finally tracks down the culprit, her half-sister April Moriarty, whom she finally confronts. But just when she thinks she has finally uncovered the truth, Charlie has to confront new secrets from the past.
