A mysterious pulse, transmitted through the global cell phone network, instantly reduces the connected population to mindless, homicidal maniacs. Graphic artist Clay Riddell, played by John Cusack, finds himself stranded in a Boston airport as civilization crumbles into bloody chaos. Teaming up with a pragmatic train conductor, Tom McCourt (Samuel L. Jackson), Clay embarks on a desperate journey north through the New England wasteland, hoping against hope that his estranged wife and son have been spared. Their perilous trek is a relentless fight for survival against the savage "phoners," but as the survivors begin to uncover a terrifying new pattern in the attackers' behavior, they realize the true horror may be far more organized and sinister than they first imagined. Directed by Tod Williams and based on the novel by Stephen King, this chilling horror film plunges viewers into a world where our most essential tool becomes the instrument of our annihilation, exploring primal fears in a landscape of modern terror.
