A psychiatrist asks one of her psychology students, an ex-police detective, to shadow her a few nights. She fears she has split personality and may have killed someone. The student has a crush on his cute teacher and says yes.

The ex-cop Tom Beckwith has just quit his police job in order to study psychology. But his professor, Lauren Porter, is more interested in his criminology abilities than in his progress in psychology. Because of traumatic circumstances during her childhood she is suffering from Multiple Personality Disorder, and it looks like her other ego has just killed somebody. So Tom Beckwith tries to help her by observing her, combining his professional abilities as an ex-cop and his recently gained knowledge of psychology.—Volker Boehm
