The ordinary day of New York City subway dispatcher Walter Garber is thrown into chaos by an audacious crime: the hijacking of a subway train. Ryder, the criminal mastermind who leads the highly-armed gang of four hijackers, threatens to execute the train's passengers, unless a large ransom is paid within one hour. As the tension mounts beneath his feet, Garber employs his vast knowledge of the subway system in a battle to outwit Ryder and save the hostages. But, there's one riddle Garber can't solve: even if the thieves get the money, how can they possibly escape?
