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.

When the town's water pressure mysteriously drops and two teens go missing – one from a pool and another from a school washroom – the gang begins to suspect something fishy's going on in Whitechapel…or is it something alligator-y? Rory confesses to flushing two baby alligators during last year's locker search at the same time that Benny flushed one of his magic potions. When Erica is attacked at the school car wash, they realize they're now battling two very angry alligators AND their evil mutant mega spawn. And the citizens of Whitechaple are about to be the gators' next meal!
