Directed and co-written by Sophia Takal, "Black Christmas" begins with Riley Stone and her Mu Kappa Epsilon sisters preparing to deck the halls with a series of seasonal parties. However, a black-masked stalker begins killing sorority women. As the body count rises, the squad starts to question whether they can trust any man. Whoever the killer is, he's about to discover that this generation's young women aren't about to be anybody's victims.
