Hostile Advances: The Kerry Ellison Story (1996)

Kerry Ellison, a vibrant young woman working as a senior accountant at the IRS, finds her life threatened by a disturbed, married co-worker who starts stalking her—following her, and writing her sexually tense notes. She makes it clear multiple times that she is not interested in him, but he is unstoppable. There's no one who can help her, so her only option is to file a sexual harassment suit against her employer and go to court, a decision that will surely cost her job. Based on a true story.
