When Mr. G unearths a mysterious crystal skull from his garden and brings it to school, he inadvertently summons an ancient Mayan Sky Queen who takes over his classroom. She entrances all the males in the school to help her prepare for a ritual that will unite her with the Sun King and end the world. At first jealous, Sarah and Erica soon realize it's up to them to save the school – and the planet – from the Queen's apocryphal plans. They ask themselves what Ethan and Benny would do and, with Grandma's help, make a plan to block the sun, channel the moon, and save the day.
As a new school year begins, Ethan and his pals haven't seen Sarah since her dramatic transformation into a full vampire months earlier. She finally reappears on the scene, ready to 'move ahead' with her life and her education, almost as if nothing had happened. Is it a coincidence that numerous vampires are being mysteriously attacked at the same time? The Council begins to suspect that either Ethan or Sarah is to blame, and they must clear their names if they want to survive. Meanwhile, a desperate former Dusk actor appears in town seeking publicity, and instead gets too much information about the Real Vampires of Whitechapel thanks to his number one fan, Erica.
