Lost in a cemetery, Alissa stumbles into an underground crypt, where she finds a veined purple plant growing up through the lid of a casket. Weirdly compelled, she opens the coffin, cutting off the growth which had wormed its way into the heart of the young corpse within. Soon, the hypnotic plant has taken hold of Alissa, too: Seduced by visions, she starts to lose sight of reality. And her kiss now carries a terrible power. Can her best friend, Evelin, save her from her strange, consuming passions--and from Simon, her crazed stalker ex?
