Marcus parts 1 &2 are 19 and 20 (final one) Gaspard's brother is in the bar here and only comes in the scenario way inside season 2, NOT in episode 2. We only miss the link with the end of episode 18 storywise.
One event follows another. An already complicated and sensitive investigation, leads the police to another, older unsolved case. Contrary to what the brigade had supposed, Marcus, the officer from the General Inspectorate, turns out to be a particularly skilful investigator. The group now works together, behind the Chief Superintendent's back.
Blood cradle (1): Jackson, also transferred to Réunion Island, joins the team after a three-month absence. Clarissa is more than surprised to meet Florian again, the husband she believed to have died two years ago. Gaspard and Jackson head a particularly sensitive case: the murder of a young woman and her baby's disappearance.
Blood cradle (2): Kelly returns to the team after leaving them without news for three months. The current investigation is going nowhere. And what if the victim's death wasn't murder after all? With the return of her husband, Clarissa has to put an end to her relationship with Raphaël.
The new savages (1): Kelly, still determined to resign, discovers six bodies when out for a walk. A new investigation that rekindles her enthusiasm for the job and leads her to rethink her decision. A seventh body is found.
The new savages (2): The relationship between Florian and Clarissa is becoming increasingly tense. And things aren't much better between Florian and Agathe: after a two-year absence, father and daughter are finding communication more than difficult. Out in the field, Jackson is on the trail of a killer carrying out a series of murders.
The Garden of Eden (1): A gardener is found impaled by a fork. Two suspects: a pensioner, who was apparently his partner, and a young woman said to be his former girlfriend. Kelly's future replacement is presented to the brigade.
The Garden of Eden (2): Kelly has finally resigned, and plans a world tour with Édouard. But Jackson doesn't like the idea one little bit. In the investigation into the gardener's murder, the younger of the suspects did indeed drug her lover, but didn't kill him. It's time for a reconciliation between Clarissa and Raphaël.
Killing Willy (1): The body of a certain Willy has been found in a car, no doubt tampered with to cause the accident. Clarissa investigates a sexual predator, whilst Jackson has to protect the sole witness for another case. Raphaël has joined the brigade permanently as superintendent, but relations with Clarissa are tense.
Killing Willy (2): As the investigation into Willy's death concludes, relations remain complicated between Raphaël and Clarissa. Gaspard is surprised to discover that his brother is on Reunion Island. Jackson falls under the charm of the person he has been charged with protecting.
Armed combat (1): A check-out assistant has been killed in a mini-market. But the rising number of thefts and assaults in the district suggest it's more than just a simple hold-up - Jackson is becoming increasingly attached to Chris, who he is supposed to be protecting. Feelings that might well go against him.
Armed combat (2): Investigating the death of the check-out assistant, the brigade quickly realises that the neighbourhood has been abandoned by the state for far too long. Joséphine intervenes to mediate between Gaspard and Douglas, notably criticising her boyfriend for making no effort with his brother, a former offender.
Too close for comfort (1): Clarissa is working Florian, her ex-husband, to investigate the murder of a former neighbour, a doctor accused of sexual assault. Édouard is making a documentary about the brigade, an opportunity for him to get closer to Kelly. A second body, linked to the first victim, has been discovered.
Too close for comfort (2): As the double murder being investigated by Clarissa and Florian is about to be solved, Jackson is still on cloud nine, convinced he has finally found perfect love with Chris. Which leaves Kelly feeling distraught.
The mystery of Étienne Franck (1): A body sent for autopsy has disappeared, along with Bernard, the forensic team's driver delivering it. The team is worried: the more time passes, the lower the chances of finding Bernard alive. Jackson begins to have doubts about Chris when it turns out that the stolen picture is a forgery.
The mystery of Étienne Franck (2): Bernard's death has shaken the entire brigade, particularly Joséphine, who feels to blame for her friend's death. As Kelly wants to give her relationship with Édouard yet another chance, the romance between Raphaël and Clarissa becomes common knowledge. Jackson decides to investigate Chris.
Next to my heart (1): Kelly, investigating the murder of a football captain, follows a trail that leads to the blackmailer who had written to the victim after her liver transplant. Could it be a serial killer? Jackson catches Chris red-handed as she's about to leave the island.
Next to my heart (2): A second victim, who had also received a transplant from the same donor, is found: the killer has to be someone close to the donor. Two suspects: the very religious and somewhat delusional father, and the jealous paranoid ex-husband.
A hike to the death (1): A family man is found dead during a hike. The clues lead to two brothers who have been robbing walkers, but they have an alibi. Yet the victim's wife had managed to describe them in surprising detail. Louna, Agathe's best friend, is sexually assaulted during a casting session.
A hike to the death (2): Whilst the widow of the murdered family man is taken into custody, her son confesses to having killed him and makes a statement that shakes the entire team. Agathe and Raphaël manage to catch the man who assaulted Louna, who was obviously not his first victim.
