Anna, a fortyish librarian who is recently divorced, goes on a date with Martin, a middle-aged perpetual bachelor. After a little sexual groping, she is ready to call it quits. Instead, he rapes her. As she recovers from her shock over the incident, she contemplates what would constitute a similarly invasive humiliation for a man, asking herself the question, "can a man be raped [by a woman]?" Donning a good disguise, she begins to stalk Martin, causing him considerable discomfiture. (fandango.com)
