Dead Tone (a.k.a. 7eventy 5ive)

Based on true events

A party. A prank phone call. A lunatic on the other end of the line.

A couple of harmless prank phone calls turn into a nightmare when a group of college friends dial a mad man. The group becomes trapped in a horrifying game of survival against a monster, hell-bent on killing more than just their night of partying. Once the phone line goes dead, it's too late to escape the fun and games this maniac has in mind...
