Aenigma

After her snobby schoolmates accidentally send her into a coma, poor little Kathy has only one way to get even--with her mind! Eva, another schoolgirl, falls under the spell of Kathy's vengeful psyche, which is capable of horrible destruction using telekinesis and even killer snails to do her bidding. Soon the hallways at St. Mary's School are filled with screaming, and there's no way to escape. In the tradition of Carrie, this psychic shocker from legendary Italian horror maestro Lucio Fulci, the man behind such outrageous cult favorites as The Beyond and Zombie, is filled with the visual style and gruesome madness his fans have come to expect. Available for the first time in America, this eerie look at the dark side of adolescence proves that girls might be made of sugar and spice, but they're not always nice!
