A group of teenagers, one of them a vampire unwittingly hired by a couple to babysit their daughter in lieu of their somewhat untrustworthy son, attempt to balance battling supernatural forces with everyday high school life.
Ethan Morgan is a geeky freshman, not trusted by his parents to stay home alone with his little sister Jane. They hire Erica, a girl from Ethan's high school who is a huge fan of ''Dusk ''(a parody of Twilight (novel series)), as a babysitter. However, Erica comes across her best friend Sarah and Jesse, Sarah's vampire ex-boyfriend, on the night she is to babysit, and decides to attend a party that Jesse is throwing instead. During a fight between Sarah and Jesse, Sarah ends up at Ethan's house and tells Ethan's parents that she was asked to babysit instead. Ethan suddenly has a vision (spirituality) when touching Sarah, and notices she has no reflection in the mirror, leaving him suspicious of her. He confides this in his dorky best friend, Benny (Atticus Mitchell).
The series follows the adventures of a geeky freshman boy named Ethan Morgan, a Seer who has visions when he touches anything paranormal, his best friend Benny, a spellmaster, and his vampire babysitter Sarah as they chase down supernatural forces. They are often aided by Rory, their dorky friend who was turned into a vampire in the pilot film, and Erica, Sarah's best friend, who also became a vampire in the pilot film.
