Two Witches (1969) on Netflix

An aging, malevolent witch intercedes in the lives of two young women.

Expectant young mother Sarah is convinced she has been given the evil eye from a mysterious blank-eyed old hag while she is dining with her bullish and insensitive partner Simon. When the couple go to visit his new-agey friends Dustin and Melissa, dark forces are unleashed after an ill-advised attempt at consulting a Ouija board to allay her fears. Meanwhile, tensions grow between grad school student Rachel and her new roommate Masha after a violent incident involving a man that the strange and impulsive young woman has brought home.

However, who's that sinister stalker in the woods? As the young couple search for answers, art museum curator Rachel is unaware that there's a shocking hidden agenda behind roommate Masha's cryptic smile.
