A seemingly innocuous pastime involving fun-loving collegians and prank phone calls turns into a lethal cat-and-mouse game in this blood-drenched fright fest starring Rutger Hauer and Brian Hooks. While vacationing at a secluded mansion after finals, a group of university students dials random telephone numbers and tries to unnerve the person on the other end. But their fun is short-circuited when one of them unwittingly connects with a slasher.
