When a shadowy government program threatens to frame his estranged son for international arms trafficking, legendary secret agent Richard Brumère, known as "The Mist," is forced out of a long, quiet retirement. Played with rugged charm by action icon Jean-Claude Van Damme, Brumère must plunge back into a world of danger he left behind, navigating a Paris now populated by eccentric bureaucrats, clumsy agents, and old flames. He finds his son, Archibald (Alban Ivanov), is a hapless, anxiety-ridden young man completely unprepared for the lethal conspiracy descending upon him. Teaming up with a pair of bumbling government employees (Eric Judor and Patrick Timsit) and reconnecting with a figure from his past (Miou-Miou), the aging mercenary employs his lethal skills and decades of experience in a race against time to clear his son's name. Directed by David Charhon, this action-comedy blends explosive set pieces with deadpan humor as a father discovers that protecting his family requires one last, spectacular mission.
