Geeky teen Ethan Morgan has a hot baby sitter, which most teenage boys would think is a good thing. The only problem is that Ethan's baby sitter, Sarah, is half-vampire (hence the show's title). Sarah drags Ethan and his pals, Benny and Rory (who was recently turned into a vampire himself), into a world of supernatural battles against creatures from their nightmares in order to save their town from vampires. Sarah hopes to one day become human again so she can save her soul -- and so she can spend less time protecting the geeky trio.
An update of the classic 1980s kids' cartoon finds bumbling bionic Inspector Gadget back on the beat, lured out of retirement to save the day. He's on the trail of the evil Dr. Claw, who has reactivated his global crime syndicate MAD. As always, the gullible gumshoe at first manages to make things worse, leaving a path of destruction in his investigative wake. Ably assisting Gadget is his confident niece, Penny, and her trusty dog, Brain, a master of disguise. Now an agent in training, Penny uses her intelligence, martial arts and high-tech gear to keep her clumsy uncle safe from harm. But it won't be easy -- Penny must ward off the advances of the handsome Talon, Dr. Claw's nephew.
