Techno-thriller in which a mysterious computer program appears to infect whoever comes into contact with it. When Josh (Jonathan Tucker), a student hacker, accidentally taps into the wrong kind of wireless signal, an evil is unleashed into this world that cannot be contained. Now it seems the virus can be transmitted to humans in a number of ways; from innocuous mobile phones to e-mail devices. A suicide starts off a chain of unexplained deaths, and as the body count rises, it becomes clear that no one is immune.
