Sara is only twelve years old and there is not a computer that she cannot hack. She's even gotten into the web of New York's juvenile justice system (with good reason), but now she's in big trouble. To save her from the accusations, a mysterious lawyer arrives who is none other than the director of a secret school for young spies. Soon Sara will join their ranks and she will meet her new teammates: Kat, Rio, Paris and Sydney, all with extraordinary talents.
