Television actor Billy Warlock plays Bill Whitney, a high school student who's plagued by disturbing visions. (Yuzna credits his inspiration for these sequences to Salvador Dali's The Great Masturbator, which should give you an indication of how weird Society can get.) Bill confides in his shrink that he believes he was secretly adopted because his family seems so alien to him. He also insists he doesn't fit in with his classmates, but the scenes in which he's seen at school are contradictory to this proclamation.
What it's not so good at is its pacing and character development. Bill isn't portrayed as a teen who's trying to live his life in spite of his problems. He's portrayed as a normal teen who doesn't even think about his problems whenever they're not actively haunting him. In the normal scenes he seems like a completely different person, entirely unaffected by his life-altering troubles. This has the unfortunate side effect of making the movie feel uneven, as if they wanted half a horror flick and half an 80s comedy.
Otherwise, there's something special here. You just have to look for it sometimes.
