In a world that believes immortality is a myth, a covert team of undying mercenaries has fought to protect humanity for centuries. Led by the battle-weary warrior Andy, played with fierce intensity by Charlize Theron, this tight-knit group finds their existence threatened when a new immortal, a U.S. Marine named Nile (KiKi Layne), suddenly awakens to her power. Their extraordinary secret is on the verge of exposure, hunted by a ruthless pharmaceutical executive (Harry Melling) who sees their biology as the ultimate commodity. As they race to protect Nile and themselves, the team, including the loyal Booker (Matthias Schoenaerts) and the devoted lovers Joe and Nicky (Marwan Kenzari and Luca Marinelli), must confront betrayal from unexpected quarters and question the very purpose of their endless lives. Directed by Gina Prince-Bythewood, this explosive action-fantasy blends ancient history with modern combat, exploring the heavy burden of eternity and the bonds that are tested when survival is no longer a question.
