The Others - Season 1 Episode 7 Theta

Marian thinks joining a sorority will help her regain some normalcy in her life -- until she learns one of the sisters is under psychic attack. She befriends troubled college coed Jenny, who is plagued by chronic panic attacks of horrifying visions from her childhood that become more physically forceful and threaten her bewildered Theta sorority sisters. Marian recruits the help of the Others, who suspect that the Theta house is haunted based on a murder on the same grounds long ago, but wise old Elmer deduces that something evil from the young woman's painful past is intruding with harmful intent. This turns out to be her imprisoned father, shot by Jenny as a child when he murdered her mother and now bent on revenge.
