Unemployed girl Mia Carter wanders into the wrong penthouse suite at a boutique hotel in Los Angeles and stumbles upon the secret of A-list star Julian Vail: he is no ordinary celebrity, but a vampire heir who transforms into a tiny palm-sized bat when triggered by silver flashbulbs. After accidentally drinking moon mint black tea, Mia develops a unique blood scent that no vampire can ignore. Instead of becoming a protected prey, she negotiates with Julian's team using this secret and lands a job as his night shift assistant. Through on-set frame-ups, rival vampire suitors, neighborhood misunderstandings about her bat, and the schemes of Julian's vampire cousin, to his manager stealing the night stone and attempting to expose Julian's identity to the public, Mia navigates every crisis with evidence, contracts, security protocols, PR plans and decisive action. She can tuck the little bat into her bag and bring him home, and she can also rescue the A-list heartthrob from viral online scandals. In the end, even after the moon mint blood scent fades, Julian still chooses to stay by her side; and Mia is no longer just "the human he was drawn to", but a rising creative PR professional standing firmly under her own name.
