Scarlet, VSS's newest member, takes on her first mission— to guard Great Britain's least favorite royal, the prodigal Prince Garson, from a terrorist attack. Disguised as cocktail waitresses, the team must secretly prevent the flirty, teenaged prince from being kidnapped during a masquerade. The camouflaged international terrorists at work, the girls can handle— it's teaming up that's a problem! Brooke, Lark, and Raven distrust their newest member— not because she's a cat burglar working a plea bargain, but because she's an American!
