Dr Alan Feinstone (Corbin Bernsen) is a Beverly Hills dentist. He's rich, successful, has a beautiful wife and a palatial home. There's just one problem - Dr. Feinstone is mad about perfection. Everything in his world, from his wardrobe to his marriage, has to be as clean, neat and orderly as a row of perfect teeth and when one fateful day things aren't just so, the good doctor turns nasty... very, very nasty. Obsessed by the imperfections he suddenly sees all around him - a dirty shirt, a flirty wife, an impatient patient - Feinstone grows ever more demented. Plotting to right the wrongs that are tormenting him, he starts to fantasies about cracking people's teeth, torturing their gums and turning their mouths into a black and bloody sludge. With his grip on reality slowly loosening, the deranged dentist's twisted imaginings begin to come true... and for anyone who's not perfect, time is running out.
