American Psycho II: All American Girl (2002)

Rachael Newman has developed an interest in murders after encountering psychopath Patrick Bateman. To further study the subject, she enrolls at the university department for Behavioral and Social Sciences, under the expert leadership of former FBI agent Robert Starkman. Very certain about herself, Rachael has one single goal: to become Starkman's teaching assistant. It's a prestigious job; having that position will almost guarantee employment at the FBI. But becoming her professor's assistant is no easy task: the first trouble arises when secretary Gerty Fleck decides that she is too young for it. And Gerty Fleck won't be the only obstacle.
