The spring semester is coming to a close at a private university in Colorado. A closeknit circle of friends who have dubbed themselves the Crew, tire of studying for finals and engage in a harmless prank calling contest called 75. However in this modern version of an old prank, the calls are crueler and the stakes are higher. The rules are simple: prank call a random person and scare the hell out of them for 75 seconds. If the person laughs or hangs up, you lose. Whoever has the best scare wins. For the Crew and their friends, 75 quickly becomes a popular game on campus. But what starts as celebration, relaxation, and an exclusive round of 75 in a mansion, turns into an intense game of survival when someone accidentally calls the wrong person. Fear and mayhem spill forth with mortal con sequences as the Crew struggles to avoid their ultimate fate.
