Lost Girl follows supernatural seductress Bo (Anna Silk), a Succubus who feeds on the sexual energy (sometimes called “Chi”) of humans. Growing up with human parents, Bo has no reason to believe she’s anything other than the girl next door – until she drains her boyfriend to death in their first sexual encounter. Once she hits the road, Bo discovers she is one of the Fae, creatures of legend and folklore, who pass as humans while feeding off them secretly, as they have for millennia. Relieved yet horrified to find out that she is not alone, Bo is faced with choosing an allegiance between the Dark and Light Fae clans. Bo decides to take the middle path between the humans and the Fae while embarking on a personal mission to unlock the secrets of her origin.
