Devil in the Flesh 2

"Devil in the Flesh 2," also known as "Teacher's Pet," is 2000's direct sequel to Devil in the Flesh. Debbie has escaped from the sanitarium that she was placed in during the conclusion of the first film, taking on the identity, college, and vehicle of a co-ed that winds up being killed in a freak accident.

Debbie's plans erode as her roommate begins investigating her cover, forcing Debbie to focus on the roommate's removal.
