A New York City subway dispatcher draws on his extensive knowledge of the subway system in order to outsmart a dangerous criminal mastermind who's hijacked a subway train in this remake of the 1974 thriller inspired by John Godey's best-selling book. Walter Garber (Denzel Washington
) is drifting through his daily routine when he receives word that a heavily armed gang of four has hijacked a subway train and is holding all of the passengers hostage. Led by cunning master thief Ryder (John Travolta
), the gunmen will begin executing everyone aboard should the authorities fail in delivering ten million dollars in the space of just one hour. With the tension in the tunnels rising, Walter races to save the hostages before the shootings start. But through it all, there's one part of Ryder's plan that Walter can't quite comprehend: even if the thieves do succeed in getting their money, how could they possibly get out of the tunnels undetected?
