Pulse

The hacker Josh invades the computer of Douglas Ziegler, who is developing a powerful wireless signal, and accidentally releases a mysterious force that takes the will to live of human beings, generating a suicide epidemic and increasing the force. His girlfriend and student of psychology, Mattie, sees each one of their common friends die and the destruction of the modern world, and together with her new acquaintance Dexter, they try to plan a virus developed by Josh in the network to shutdown the system and save mankind.

Imagine our wireless technologies made a connection to a world beyond our own. Imagine that world used that technology as a doorway into ours. Now, imagine the connection we made can't be shut down. When you turn on your cell phone or log on to your e-mail, they'll get in, you'll be infected and they'll be able to take from you what they don't have anymore -- life.
