Carmie, with the help of her best friend Kev, discovers that she is a Vampling: half human, half vampire, while a descendant of the famed vampire hunter, Van Helsing moves to town.

Carmie rehearses for the musical but struggles to keep her powers in check. Kev discovers that Blendeds are going missing and there are hunters looking for kids like Carmie.

Carmie races to find a way to appear normal on-camera for her musical program photo, as Kev hunts for the Blended hunter.
