Silent Night, Deadly Night 4: Initiation

Silent Night, Deadly Night 4: Initiation is a 1990 American supernatural horror film directed by Brian Yuzna, written by Yuzna, Woody Keith, and Arthur Gorson, and starring Maud Adams, Tommy Hinkley, Allyce Beasley, Clint Howard and Neith Hunter. It focuses on a Los Angeles newspaper reporter who, while investigating the unexplained death of a woman, becomes entangled with a coven of Lilith-worshipping witches who are preparing her for a ritual on Christmas Eve. The fourth installment in the Silent Night, Deadly Night film series, it bears no resemblance to the previous films, as it drops the storyline of the Billy Chapman and Ricky Caldwell characters entirely.
