Not "Heathers" or "Pump Up The Volume", but O.K. Movie description An alienated teenager from an affluent suburban community uses his evil genius to manipulate his family and intimidate his peers, leading to a shocking climax that will take you one step beyond sanity. One evening, Phillip Collins (Dan Ziskie) & Susan Collins (Brooke Tracy) find their maid Mrs. Murdock at the end of their steps: dead, neck broken. Obviously she had an accident. Consequently they need a new babysitter for an upcoming big party. The sensible Helen Giles (Lois Smith) meets little Evelyn Collins (Tandy Cronyn) at the discount market and likes her, so she offers to do the job. She doesn't know Evelyn's teenage brother Mark Collins (Christian Slater) - technically skilled and good in school, but resistive and cunning. As soon as the parents have left, Mark starts psychologically terrorizing Helen and his sister with electronic tricks.
