Dead Tone (2007)

As another semester draws to a close at the University of Dreyskill, a simple game dreamt to help students avoid studying becomes a bloody battle for survival in this stalk-and-slash frightener from filmmaking duo Brian Hooks and Deon Taylor.

Dreyskill may have a reputation as a prestigious private school, but a group of students known as "The Crew" are sick of studying for finals and looking to have a little fun. In order to pas the time, they create a game called "75. " The rules of 75 are simple: the participant in the game calls a random telephone number and attempts to scare the party on the other end of the line for 75 seconds; should the recipient of the call laugh or hang up, the player loses, and the player with the best call emerges victorious. By the time exams are over, 75 has become a popular campus pastime among all the students, and one rich classmate invites the Crew to his massive mansion in the Colorado hills for a wild weekend of partying. But when one of the Crew accidentally calls the wrong person, the once-playful scares become all too real
