In Tandem - 3 ª Season

In Sète, the nautical tournament is an ancestral tradition as old as the grudge that animates the Caravani and the Villa, two rival families who compete for the famous Saint-Louis trophy.

Following a phone call from a woman in distress, investigators come across a murder in which all evidence points to Damien Heyrieux, a perfumer from the victim's family business. Soler and Marchal cannot find the motive for the crime or the body of Clara Séguret to prove their suspicions.

Maxime Baltard, a former prisoner famous for his escapes and who seemed to have found his redemption, is found dead on his farm where he grows cherries. Apparently, Maxime kept secrets from his family, including Isabelle, his wife, a woman who had given everything for him.

Sylvain Théron, 35, is found dead on the bank of a river where Roger Lefort, alias "Lucky" teaches a gold diggers course. Lucky found 3.8 grams a few years ago and set up a business that includes the courses, a campament and "La Pépite", a bar run by his sister Marithé. As per Théron's ex-wife testimony, Sylvain had recently got big money and told his ill 15-year-old son, Elliot, he had found a gold vein; this information made Mark, his mother's new partner, angry. Paul does not believe the gold vein hypothesis for he is confident that the river produces no gold for a value greater than 20 euros. Léa sends Lieutenant Erwan Lebellec infiltrated to prove Paul wrong. Privately, Paul and Léa remain concerned about their children's college entrance exams and Alice's boyfriend, Julien Garrido. Léa also finds out that the colonel wants to open a file on her for irregularities in investigations and to request her transfer. Her concerns lead the commander to accept yoga classes with Gregory, an instructor her mother has found for her.

François Durieux, concertmaster of the Marseille Opera Philharmonic Orchestra, is found stabbed with a luthier's knife. His acquaintances and family agree that he was a very talented and lonely young man, whose only passion was music and his "Armanello", a prestigious violin from the 18th century.
