1985 Season 1

Friends Marc and Franky start a career with the Gendarmerie. The corps is in a deep crisis after an internal drug scandal and Marc ends up in the middle of the internal battle within the Gendarmerie. Student Vicky distances herself from her brother Franky and Marc because they are not very popular as gendarmes on the left-wing university campus.

After the attack on Vernaillen, Marc is taken under the protection of his new superior, adjutant Goffinard. Franky then jumps into the breach for his boss, adjutant Debels, who went far over the line in a racist incident. Madani Bouhouche wants revenge after his dismissal from the Gendarmerie.

Marc and Goffinard discover an unexpected connection between several serious crimes. Goffinard wants to keep their research quiet as much as possible, to keep everything in their own hands. Franky gradually becomes more and more entangled in the extreme right-wing network, even though he does not yet know exactly what it entails or where it could lead.

During a fierce demonstration, Marc as a gendarme and Vicky as an activist are opposed to each other, which strangely enough strengthens their bond. As a reward for his discretion, Franky is allowed to work with the Brigade Diane. Vernaillen secretly conducts a parallel investigation.

Marc and Vicky's fledgling relationship is strained by their diverse backgrounds and political differences. Franky is allowed to work as a security agent at a private party of a minister, which brings him even closer to the extreme right-wing leaders. Another bloody attack is committed, further escalating the situation.

Vicky graduated as a lawyer and now lives with Marc. He secretly investigates the Gang with Goffinard. Vernailing is promoted away. The Group G thinks that Marc is getting too curious about their activities. They send Franky after him.

After several deadly attacks, it suddenly becomes quiet around the "Bende van Nijvel" gang, and the investigation therefore comes to a standstill. Marc has to do administrative work, much to his frustration. When Vicky receives an interesting assignment, he hopes she will pass on information to him, but he has not counted on her professional secrecy. Franky is increasingly fleeing into hard drugs.

Bouhouche is arrested for the murder of his friend Mendez. Together with Goffinard, Marc eavesdrops on the prison conversations between Bouhouche and his wife, which yields important information. For a moment it seems that they can really catch the Gang now, but then it comes to a shocking confrontation.
