During a covert operation in Niger, French intelligence agent Mata is wounded and witnesses her colleague Antoine being captured right before her eyes. Upon returning home, she volunteers for a counter-espionage mission in the Alps, driven by the suspicion that this new assignment could be linked to her traumatic African mission. Haunted by Antoine’s imprisonment and convinced that her superiors are withholding vital information, Mata embarks on a solitary, high-stakes chase against the clock. Operating outside official channels, she risks everything—her safety, her career, and her very life—to uncover the truth.
