The bustling chaos of Paris’ Gare du Nord – Europe’s busiest train station – is the setting for Marion, a taut, six-episode French crime series adapted from the novels by acclaimed author Danielle Thiéry.

At the heart of the drama is Edwige Marion (played with steely resolve by Louise Monot of Murder In… and OSS 117: Lost in Rio fame), a no-nonsense police commander freshly transferred from Lyon with her adopted teenage daughter. Thrust into leading the train squad at Gare du Nord, she inherits a team of battle-hardened cops navigating a gauntlet of urban crimes: drug trafficking in the shadows of platforms, human smuggling amid the commuter crush and brutal assaults in forgotten corners.

The show’s strength lies in its unflinching gaze at the station’s dual nature: a gateway to dreams for travelers, but a grim arena for the vulnerable. Marion’s methods are as sharp as the winter chill seeping through the concourse: she’s intuitive, relentless and unafraid to bend the rules while juggling motherhood in a high-stakes world that blurs professional and personal lines.

French critics hailed Marion for its atmospheric authenticity – filmed on location in Villeneuve-Saint-Georges to evoke the real grit of Gare du Nord – without romanticizing the violence. Unifrance called it “a dark thriller driven by a strong female lead” and praised its balance of procedural precision and emotional rawness. French reviewers on AlloCiné echoed this and noted the “convincing performances” and “sombre ambience” that make it a standout in the police procedural genre akin to Spiral – but confined to the rails…
