Heather Graham is the successful psychiatrist "Elizabeth" who finds her daily routine interrupted by a visit from the seemingly paranoid "Asa" (Judah Lewis). Initially sceptical, she begins to become intrigued with his story that he is being persecuted by a man, on the phone, who is threatening him. Indeed one such call induces a sort of fit from the young man! A visit to his home, and she is hooked into a mystery that is somewhat reminiscent of "Fallen" (1998) as it turns our erstwhile respectable physician into someone reduced to some rather lively, impromptu, nookie before incarceration in a padded cell trying to convince her close friend "Dr. Dani" (Barbara Crampton) that she's not completely deranged. This starts off quite interestingly, with a solid effort from Lewis as the troubled youth - but as it progresses and it becomes clear to us just what is going on, the film begins to fall away and lose any potency. The last half hour is violent and brutal, but suffers from a lack of plausibility - in this or any other dimension - and it becomes repetitive and shows up the really mediocre quality of both the writing and the acting. It is watchable, if only for Lewis, but equally forgettable stuff.
