碧姬（艾米莉·帕金斯 Emily Perkins 饰）和金杰（凯瑟琳·伊莎贝尔 Katharine Isabelle 饰）是情同手足的姐妹，彼此之间感情十分亲密。某日，金杰外出意外遭到了一只怪兽的袭击，好在虽然身受重伤，但好歹捡回了一条性命。然而，令碧姬感到担心的是，自此金杰的性情大变，日渐放荡狂野，不仅四处沾花惹草，甚至开始渴望鲜血的滋味。 让碧姬感到更加恐慌的是，她发现金杰身上已经愈合的伤口之上竟然长出了褐色的毛发，而她的尾椎骨上亦身处了类似尾巴一样的部分。无法对此坐视不管的碧姬找到了喜欢研究植物的山姆（克里丝·莱切 Kris Lemche 饰），希望后者能够研制出解药，让金杰变回原样。Is becoming a woman analogous, in some deep psychological way, to becoming a werewolf?
