Paris, 1960. André Merlaux is hired as a trainee at the French secret service under the seasoned eye of several elite agents and a formidable colonel.

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.

On a mission to Moscow with Merlaux, Calot stirs up trouble with the CIA. Marie-Jo's upcoming promotion creates a mini-crisis at 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.'

Moulinier, Jacquard and Calot go on strike to protest the loss of a bonus. Barred from seeing Sophie, Merlaux dives into his work and uncovers a plot.

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.

Determined to get rid of Merlaux, the Colonel sends him to Algiers to stake out the mole, all the while plotting a devious surprise.

Calot, Moulinier and Jacquard fly to Cuba to rescue a missing agent, only to find she doesn't want their help. The Colonel lays a trap for Moïse.

As France votes on Algeria's future, Jacquard hatches a crooked scheme, André works to free Moïse, and Sophie springs a surprise on her family.

The Colonel orders his henchmen to take out André, Marie-Jo uses her baking to gather intel, and a delegation from Quebec asks the agency for help.

A shocking announcement leaves André confused. After laughing off Calot's warnings about the Cold War, Moulinier ignites a major international crisis.

During a mission to Algeria, the Colonel's strange behavior prompts Jacquard to take a drastic step. André makes contact with a mysterious figure.

While Jacquard and Moktar transport the bomb -- and the unraveling Colonel -- across the desert, Moulinier falls head over heels for his target.

Tasked with choosing a new president for an African nation, Moulinier follows his heart. Meanwhile, André faces yet more grueling tests.

Ahead of a visit from the Kennedys, two CIA agents try to stamp out any hint of communism at the agency. The Colonel sics a surveillance team on Irène.

While Calot schools his colleagues in the curious ways of the Eastern bloc, André tours the nerve center of the KGB.

The Colonel threatens to reveal Moïse's secret if he doesn't deliver André within 36 hours. The shoe incident leads to historic repercussions.

While the real mole attempts to eliminate André, Moïse gains some leverage of his own, and the Colonel seeks a solution to his wedding problem.

Hijinks and revelations abound as André hops a train in Algeria in search of the mysterious Yannick -- with the other agents in hot pursuit.
