The Signal (2007 film)

The Signal is an American horror film written and directed by independent filmmakers David Bruckner, Dan Bush and Jacob Gentry. It is told in three parts, in which all telecommunication and audiovisual devices transmit only a mysterious signal turning people mad and activating murderous behaviour in many of those affected.

The film opens, showing that Mya is cheating on her husband Lewis with a man named Ben. Ben attempts to convince Mya to leave the city with him, but she remains noncommittal. As Mya exits, Ben turns the television on and watches a bizarre, psychedelic sequence of images. Mya begins to listen to a compact disc given to her by Ben, but she is menaced by men who are acting strangely in a parking garage. When she reaches her apartment building, she finds more people behaving strangely. Unknown to Mya, the Signal, a staticlike interference that is coming through the television, radio and telephone amplifies each persons negative emotional traits, causing them to act irrationally and, in most cases, violently.Once inside her apartment, Lewis and two friends, Jerry and Rod attempt to fix the TV, but Lewis, the first to react to the Signal, beats Jerry to death with a baseball bat over a minor argument. Mya flees in panic, leaving Rod and Lewis in a struggle, but finds the whole building in chaos with people killing each other. Mya hides out in the nearby apartment until morning. When she decides to leave and reenter her home, she finds an unconscious Lewis, bound to a chair with ducttape. He awakens only to see her leave him behind and exit into the hall listening to Bens compact disc, but encounters Rod who drags her into a janitors closet. He then tells her of the night he spent trying to survive in the apartment complex. It becomes evident that the Signal affects each person differently, and that there is the possibility that Rod is also crazy, though he seems to largely have control of his own judgment. Together, they escape, and attempt to drive to safety. But after being shot by a policewoman and almost left behind by Mya, Rod becomes even more violent and attacks Mya, who crashes the car. Rod is incapacitated and trapped in the vehicle, while Mya flees, telling a stranger named Clark that she is going to the train station. ........
