In escaping from the killer, a blow to the head leaves Anna with a neurological disorder which means she cannot remember faces. Every time she looks at a face, it changes to such an extent she is unable to recognise even her boyfriend, nor her best friends.
Working out the identity of the killer is even more difficult.
Only one face helps her through her life-and-death quest for answers - Detective Kerrest (Julian McMahon).
They must put the pieces together before the killer eliminates the only witness to his crimes - Anna.
