When he is betrayed and wrongfully imprisoned, he must use his intimate knowledge of the fortress’s blueprints to orchestrate a daring escape. Teaming up with a cunning and resourceful fellow inmate, portrayed by Arnold Schwarzenegger, the pair must navigate a labyrinth of treachery, sadistic guards, and ruthless prisoners. As the clock ticks down, their unlikely alliance is tested by hidden agendas and brutal obstacles. This taut action-thriller blends cerebral strategy with explosive physicality, delivering a pulse-pounding journey through a concrete nightmare where survival demands both brains and brawn.
