When LA's vampires, witches, and werewolves make a mess, they call Scarlett Bernard to clean it up. Her ability as a null erases all magical traces from anything - or anyone - that comes within ten feet of her, and keeps humans in the dark about the city's paranormal activity. One night when she's called to a grisly crime scene, Scarlett is spied by the all-too-human LAPD cop Jesse Cruz, who strikes up a deal with her: he'll keep quiet about the supernatural underworld if she helps him crack the case. She agrees, but the city's chief vampire, Dash, starts to suspect Scarlett is behind the murders and will reveal all she knows of his shadowy empire. Now it'll take more than Scarlett's unique abilities to clear her name, keep the underworld underground, and track down the real killer.
