Au service de la France

André Merlaux, 23 years old, arriving from Algiers to enter the Ministry of Defense as french intelligence services' agent. The operations director, Moïse, gives Merlaux under responsibilities of Moulinier, Jacquard and Calot.

Moulinier and Jacquard cause a diplomatic incident while trying to capture a high-value target. Merlaux meets the enchanting Sophie.

When an African state demands independence, Merlaux gets his first big assignment and discovers a passion for politics.

Joining Jacquard in Algeria for some real-world training, Merlaux faces the darker side of a spy's life for the first time.

Calot runs afoul of the CIA while on assignment in Moscow; Marie-Jo's promotion rattles the office.

While the senior agents compete for the role of assistant director, Merlaux tries to figure out what Sophie means by the term "modern woman."

The discontinuation of salary supplement VG 42 leads to a strike among the senior agents.

After discovering that Merlaux is still seeing Sophie, the Colonel sets a trap for him under the guise of a high-stakes solo mission.

Sent to Algiers to intercept a terrorist, Moulinier and the others go to extremes to wrap up the mission and make it to a rugby match.

Determined to flush out the mole in the secret service, Moïse borrows a lie detector from Mossad, which immediately puts the Colonel on edge.

The hunt for the mole awakens Calot's paranoia, the Colonel discovers just how much Moïse knows about his past, and Merlaux opens up to Sophie.

The Colonel tries to get Merlaux out of his hair by sending him to Algiers to track the mole.
