Wounded during a secret operation in Niger, French intelligence agent Mata is forced to leave behind her colleague Antoine after he is captured during the mission. Back in France, she volunteers for a dangerous counter espionage assignment in the Alps, sensing that the new operation may be connected to the events that nearly destroyed her in Africa. Still haunted by Antoine’s capture and increasingly suspicious that her superiors are deliberately keeping crucial information from her, Mata decides to investigate on her own. As she follows a trail of hidden clues and unanswered questions, she finds herself caught in a race against time, operating beyond official orders and risking her career, her safety, and everything she has left.
