The CIA only hires the best. Top operative, JJ, has proven that he has the skills needed to be a fantastic spy. There's only one problem: JJ's so hardened by the life that he's not good with people and tends to kill first and ask questions later. JJ's boss thinks that his soldier-like behavior makes him unsuitable for intelligence work. He sends JJ on one last mission to prove his point. JJ and his partner must monitor a family. That's it. When nine-year-old Sophie stumbles across the operation, JJ makes a deal with her to maintain their cover. He agrees to teach Sophie how to be a spy. What JJ doesn't realize is that Sophie has decided to teach him some people skills, including how to have fun.
