Starla (Jane McGregor) is a cut-out-and-keep teen queen. Cheerleader? Check. Dorky brother? Check. Dumb folks? Check. Into this plastic-fantastic life comes French exchange student Genevieve (Piper Perabo). Genevieve speaks odd English, is ugly-but-cute and aims to take over Starla's world like an extra from Invasion Of The Body Snatchers.
Making much of Starla's airheaded universe, Slap Her is so clueless, it's untrue. Okay, Perabo has some pep but, after an hour of dimwitted daftness, not even she can alleviate the boredom.
