Exclusive: Get a Sneak Peek at Kelly Osbourne on CSI: Cyber

Osbourne's character, Stella Kaine, is an Internet assassin - a black-hat hacker who "kills" people digitally, by clearing their bank accounts, deleting social security numbers, filing false death certificate, and basically making it look like they never existed.

[...] when Avery's (Patricia Arquette) ex-husband becomes the target of one of these identity erasures, Stella is exactly the type of person they need to turn to for help.
