Heilo Lee is a vampire hunter who hasn't slept well since his family was killed in the middle of the night. Determined to discover the identity of the assailant, Heilo accepts an undercover mission in which he must kill Harace Rivera, president of the Rivera family business. But when Harace takes an interest in Heilo and makes him his secretary, he begins to fall for the man he’s supposed to kill.
