A beautiful model, desired by the all the men that she meets, begins to receive obscene phone calls, which, as they become ever more menacing, start to take a toll on her wellbeing, in this diverting but vaguely implausible little thriller. Though it remains thoroughly unpredictable throughout, the performances of the cast, playing somewhat unconvincing characters, are (barring the excellent Angelis) only ever adequate at best.
