Bo's friends are having too much fun celebrating the Yule to realize that she's gone missing. But when the night starts repeating itself, Bo makes it her mission to stop it. Meanwhile, Lauren and Dyson disagree over a mysterious package addressed to Bo.
Bo is a Succubus, a supernatural seductress, who feeds on the sexual energy of humans. Growing up with human parents, Bo had no reason to believe she was anything other than the girl next door - until she drained her boyfriend to passing in their first sexual encounter. Now she has hit the road alone and afraid.
She discovers she is one of the Fae, creatures of legend and folklore, who pass as humans while feeding off them secretly and in different ways, as they have for millennia. Relieved yet horrified to find out that she is not alone, 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.
With the help of her human sidekick, Kenzi, and Dyson, a sexy police detective, Bo takes on a challenge every week helping a Fae or human client who comes to her to solve a mystery, or to right a wrong.
