Following on from My Babysitter's A Vampire The Movie and armed with their newly found supernatural powers, Ethan and his buddies are dragged into a world of wild supernatural creatures straight out of their nightmares. Now Ethan not only has to take on demons, ghosts, werewolves and zombies, he still has to get his homework done on time and be in bed by 10. Ethan also discovers that he's a 'seer', who gets flashes of the future when he touches anything or anyone with other-worldly energy, and it turns out Benny's grandma is an 'Earth Priestess' (aka 'Witch') and she's teaching him the spell-casting ropes. Caught in the middle is Ethan's vampire babysitter, Sarah, who desperately struggles to resist the fang-frenzy that's taking over the town of Whitechapel - including her own BFF, Erica. Sarah hopes that one day she can be human again so that she can save her soul, finish High School, and - best of all - spend less time protecting three of the nerdiest 9th graders she's ever met.
