American Psycho II: All American Girl (2002)

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