Radio station GBS needs sponsors. Fast. Reeling from the death of one of its founding members, the station is barely getting by. As the new management is about to make what seems an unsavory deal with the suspicious man named Scarpelli, one of its employees, Melvin Mansfield, unexpectedly finds himself about to inherit a fortune from his late Uncle Ferdinand. According to the will, however, he must spend Halloween weekend at Ferdinand's upstate New York estate, where ghostly appearances have recently been reported. A publicity stunt is hatched for the entire cast and crew of GBS to stay the weekend and transmit live shows from the Mansfield mansion. Soon Melvin and the GBS employees are facing attempts on their lives, witnessing supernatural occurrences, and confronting their deepest fears. Who among them will survive?
