Terrible Delights #41: Black Christmas

This week's pick is the 1974 Bob Clark-directed slasher Black Christmas. As winter break begins, a group of sorority sisters begin to receive anonymous, lascivious phone calls. Soon, one of the sisters goes missing from the sorority house, and a local adolescent girl is murdered, leading the girls to suspect a serial killer is on the loose. But no one realizes just how near the culprit is.
