Being permanently based in a local New York City high school as an undercover operative has its moments, good and bad, for 16-year-old safecracker Maggie Silver. Pros: More quality time with her former mark-turned-boyfriend Jesse Oliver and insanely cool best friend, Roux. Getting to spend quality time with her semi-retired and international spy honorary uncle, Angelo. Cons: High school and the accompanying cliques, bad lunches, and frustratingly simple locker combinations. But when Maggie's parents are falsely accused of stealing priceless gold coins, Maggie uses her safecracking skills to try and clear their names. Too bad it only serves to bring the wrath of the now corrupt Collective down on all of them. Can Maggie and her "new team" defeat their former allies?.
