The episode opens at the Hôtel Bartoli, where Louise is increasingly suspicious of Théa, her niece, suspecting her to be the mysterious "corbeau" (the crow) who has been sabotaging the family and the hotel. Louise confronts her son Gabriel, asking if Théa might have accessed her computer while cleaning her apartment, as Théa's arrival coincided with a recent fire at the hotel. Louise instructs Gabriel to keep an eye on Théa, heightening the tension within the family.

Meanwhile, at the hotel reception, Jade is interrupted from her reading by Emilia, a guest who requests to extend her stay. At the same time, Joey aggressively demands the suite number 5, which is still occupied by Robbie. Jade informs Joey that the suite remains unavailable, but Joey insists she must have it by that evening, escalating the pressure on Jade.

Magalie begins her physical rehabilitation with Tarek, who encourages her to overcome the trauma caused by the recent fire. Magalie emotionally recounts the fear she experienced during the incident and expresses guilt for not being able to return to work, feeling she is letting her colleagues down. Tarek advises her to stop blaming herself and focus on recovery.

Back at the hotel, Louise and Théa are faced with a new challenge when a timer suddenly activates in a hotel room, giving them five minutes to solve a puzzle. Louise notices a painting in the room depicting two figures playing chess, which seems out of place. Recognizing that "le berger" (the shepherd) is a chess move, they rush to the garden where a giant chessboard is set up.

They begin flipping the chess pieces and discover a hidden phone beneath them. As the timer runs out, the phone screen displays a red smiley face followed by an arrow, indicating a message has been sent. Almost immediately, both Louise and Théa receive notifications on their phones. Nearby, Kim reacts with a startled cry upon seeing the message's content, signaling a new twist in the unfolding mystery.

Throughout the episode, the atmosphere at Hôtel Bartoli grows increasingly fraught as Louise grapples with the possibility that Théa is betraying the family, while Magalie struggles with her trauma and the pressure to return to normalcy. The episode ends with the revelation of the cryptic message, setting the stage for further conflict and suspense.

In Episode 3 of Nouveau Jour, Louise suspects Théa of being the 'corbeau' (the mysterious figure threatening the Bartoli family and the hotel). This suspicion arises because Théa does not talk about the countdown or the fact that someone has taken something from the estate, which makes Louise wary and leads her to ask her son Gabriel to keep an eye on Théa, especially since her arrival coincided with a fire incident.

In Episode 3, Jade is struggling to satisfy Joey, who is upset because the suite number 5, which Joey wanted, has been given to another client named Robbie. Jade is trying hard to manage the demanding clients, including Joey, who keeps pressing for the suite.

Magalie begins her rehabilitation with Tarek and emotionally shares how traumatized she is by the fire. She feels guilty for not being able to return to work and fears she is letting down her colleagues, indicating her internal struggle and doubts about her recovery and role at the hotel.

Louise confronts Théa indirectly by questioning her about the countdown and the missing item from the estate, which Théa avoids discussing. Louise's suspicion grows, and she involves her son Gabriel to monitor Théa, especially since Théa's arrival coincided with the fire, suggesting a growing mistrust and tension between them.

In Episode 3, the hotel Bartoli faces escalating threats from the 'corbeau,' intensifying the pressure on Louise, who feels overwhelmed by the situation. Meanwhile, Magalie is trying to find a new start despite her trauma, Jade is dealing with difficult clients like Joey, and the family dynamics are strained by secrets and suspicions, all contributing to a tense atmosphere at the hotel.
