A teenage spy is assigned her very first undercover mission, which consists of catching an enemy teen spy and recovering a phone virus.

K.C. tries to persuade her parents that her younger brother Ernie is ready to be a spy. But Craig and Kira are instead adamant about introducing them to their "little sister" humanoid robot, Judy.

K.C. agrees to try out for the cheerleading squad to spend more quality time with Marisa. Meanwhile, Craig tries to use sports to bond with Ernie.

K.C. and Ernie work with their ex-spy grandparents to save Kira and Craig from a dangerous task.

Marisa is a finalist in a photo contest and if she wins, the photo could be on billboards everywhere. The problem is, however, that the photo is of K.C.

K.C.'s confidence is shaken after she makes a mistake on a mission, so Marisa makes it a mission to help her best friend get her game back on.

The Coopers are assigned Prince Promomomo's security and he has to stay with them for a while. However, Craig loses it when K.C. and the Prince become enamored with each other.

K.C. is scolded by Agent Beverly for not turning in her last mission report, which Marisa mistakenly turned in as her class paper. So the girls race against time to bring it back.

K.C.'s awkward brother Ernie brings home his new girlfriend Jolie, who is smart and beautiful, and K.C. believes she is a spy.

K.C. ends up falling for Brett Willis, a renowned junior spy who is posing as her boyfriend on a mission. Meanwhile, Craig and Kira find out that their arch nemesis Zane is back after them.

Zane has abducted K.C. and replaced her with a K.C. look-alike to take her place and destroy the Coopers.

K.C.'s look-alike manages to gain access to the Organization and K.C.'s parents must rush to save both their daughter and the agency.

K.C. resolves to take a much-needed vacation so Ernie steps up and decides to prove himself to his sister and father during a stakeout to catch a notorious thief.

K.C. enlists her father to establish a neighborhood watch group when the house of their neighbor, Mrs. Goldfeder, is robbed.

K.C. is assigned to guard the President of the Organization's daughter Eliza, so she goes undercover as a student at the University of Maryland.

K.C. and her mother go on an undercover mission at a prison, and they must stand against each other as K.C. is posing as a dangerous criminal and Kira as a correctional officer.

K.C. goes further undercover into the Other Side's training field and is very close to getting the information she needs, but she is surprised to find that Brett is the officer training her.

While on a much needed family vacation, the Coopers find that trouble follows them wherever they go when a socialite disappears from their hotel.

Kira dupes K.C. into taking part in a mother-daughter ball by saying it's an undercover mission. However, Kira is disappointed when K.C. asks for Marisa's help to dress her up.

K.C. poses as a male cadet alongside Ernie on a mission to save an agent's son at a boys' cadet academy.

Judy runs away and is caught by enemy spies, so K.C. asks former spy and computer expert Simone Deveraux for help.

K.C. and a special guest travel to Alaska to save Judy when they find out that she has been taken there by the Other Side.

Ernie and Judy travel to NYC for a Halloween party in Central Park to stop an evil wolf serum. However, they're interrupted by Emma and Zuri, whom they meet at the party.

K.C. and Ernie must set aside their rivalry and join forces to be able to escape the bank vault in which they're trapped.

Kira is arrested by the Organization for being an enemy of the state and Maggie Summers arrives to help K.C. prove her mother was set up, but is she really helping?

K.C. surprises Craig with a visit from his father Earl, but she is surprised to find they don't get along, and her Poppa Earl has no clue they're all spies.

Brett returns and is assigned to get rid of K.C., but he can't do it. That's when she decides to protect him from the Other Side.

K.C. recruits her family to aid in Brett's escape from the Other Side. However, this endangers the Coopers as enemy agents as well as the Organization go after them.
