A once peaceful city has fallen into the hands of an evil naga ruler, and now this sanctuary is anything but a safe home for supernatural beings. Things get worse when the naga joins forces with a human scientist to create a state-of-the-art android, a prototype weapon designed to stomp out even the thought of rebellion.
But the evil lord has a problem: his own son, a mermaid-naga hybrid with a fiery temper and inability to follow rules. As the human-sized deadly weapon becomes his new babysitter, an unexpected bond forms between them and the two have to stand up to the evil lord or lose their freedom for good. Joined by a werewolf soldier and a dying vampire doctor, these unlikely allies are set to save their beloved home and free their kind from the torment.
