Hex

HEX weaves the chilling story of one girl's exploration of the supernatural around the tale of her own sexual awakening at a remote English boarding school. When social outcast Cassie Hughes unearths hidden ancient artifacts, she gains otherworldly powers with a terrifying link to the past. Though these newfound abilities frighten Cassie, she cannot deny that they make life with her irritating classmates infinitely more interesting. Her fate turns, however, when tragedy befalls her best friend, and Cassie embarks on the ultimate journey of discovery. (official distributor synopsis)
