Teacher's Pet (2000)

She gets whatever she wants...

Psychopath Debbie Strand escapes from a mental institution for the criminally insane and takes the identity of a co-ed she meets and dies out of fear of Debbie and sets herself up on a college campus where she once again begins killing students and faculty who get in the way with her obsession with her former high school teacher Sam Deckner now teaching at the college.
