When a total power black-out hits the world — planes falling from the sky, cars crashing, cell phones and computers dying — two Englishmen are stranded separately on the east coast of the US. They both try to find their girlfriend and sister, respectively, who is trapped in New York. As society quickly turns to chaos, the two men encounter violence, tragedy, friendships and adventure, joined along the way by several different characters.
Meanwhile, the girl they are making their way towards is surviving as best she can, all the while being terribly worried for her idol: Harry Styles, of the band One Direction, who was performing in New York at the time of the unexplained apocalyptic event.
