After twelve-year-old JJ Bennett lands at the airport in Berlin, he's sure something is wrong. His secret organization of kid spies, the K-CIA, hasn't had to deal with any problems in a while. When his fellow agent and best friend Maggie convinces him they should relax and go to the movies with their new friend William, JJ finally decides he's been stressing for nothing and everything is fine.
He is wrong.
The trio is kidnapped by the evil Russian spy group, the P-KGB, and JJ discovers the Russians are in town looking for something hidden in the city, something they claim could throw the entire world into chaos. Determined to keep the enemy from succeeding, the kids escape and attempt to figure out the location of the mysterious hidden item. But as the search takes them to sites all around Berlin, they soon discover that the missing object is far more dangerous than they originally thought. With the Russians closing in on them, the three friends must unravel a series of clues to keep the P-KGB spies from completing their mission--the assassination of the world's most powerful leaders.
