Kailee Wolf. The best twelve-year-old spy the FBI has. The tomboy's blue eyes and long brown hair makes her look innocent, though she's anything but. Kailee Wolf is dangerous, brave and cocky. When Kailee's boss assigns a mission to her, she expects a 'gun-knife' type thing. Not a secret bodyguard for a dumb boyband. One Direction is being threatened. She has to protect and watch them. Of course, Kailee is none too happy about her babysitting job for five full grown men. Kailee knows that this is not fun and games. It's her job to protect these boys, snotty boyband or not. Maybe Kailee will learn that looks can be deceiving and maybe the boys aren't that bad. And maybe if she's lucky, this mission might come with a 'gun-knife' type area.
