The Signal (2007)

It's New Year's Eve in the city of Terminus, and chaos is this year's resolution. All forms of communication have been jammed by an enigmatic transmission that preys on fear and desire driving everyone in the city to murder and madness. In a place once marked by conformity but now sent into complete anarchy, the rebellious Ben must save the woman he loves from the bedlam in the streets as well as her crazed sadistic husband. But the only way to tell who to trust or who has given in to violence is by uncovering the true nature of The Signal.
