High-school student K.C. Cooper is a math whiz with a black belt in karate. A normal teen otherwise, her life changes when her parents, Craig and Kira, recruit her to be a spy in a secret government agency known as The Organization. Along with her parents and younger siblings Ernie and Judy -- the latter is a humanoid robot -- K.C. must balance a civilian existence with undercover missions designed to save the world. As K.C. goes about spying, she must keep the newfound career a secret from best friend Marisa.
KC struggles to decide if she should continue as a full-time spy or live a normal life at college.
K.C. and Marisa take Amy to New York so she will not be home to witness her "parents" being arrested by the Organization.
KC saves Ernie since it was her fault the barbecue failed; the Bishops have listening devices.
K.C. continues to grow closer to Amy; bugs are planted in the Bishops' house in an attempt to get information on the weapons distribution list.
