The worst came one dark day when an EMP decimated the nation's power grid, plunging the entire country into darkness and stranding his wife and teenage son in the middle of Manhattan. Now Sam must fight his way into the city alongside his best friend Joe, a retired US Marine, to rescue his family from a lawless post apocalyptic metropolis. But when an old enemy hell bent on revenge rears his head, Sam's entire family will be placed in the line of fire.
