Joe thought he had the hang of this undercover thing. Sure, he has to dress up as a girl and change his name to "Josie" to keep his family safe, but he can still play soccer, and his new friend Sam knows his secret so he at least has someone to talk to. Not to mention, it's finally time for Joe and Sam to learn how to be proper spies…gadgets and all! Joe is prepared to prove to his parents that he's ready for a big mission. Their first mission isn't exactly what either of them had in mind, though. Joe and Sam have to go undercover . . . as ballerinas! Joe isn't thrilled about the idea of wearing a tutu, but he's more than ready to track down the potential thief of a soccer memorabilia exhibit at the local community center. He will dance like a flamingo if it means keeping the coveted keepsakes of his favorite sport safe. Unfortunately, Joe and Sam have very different ways of approaching the mission and their tactics clash. Once best friends and partners-in-spying, they now are determined to crack the case without each other. When Joe's parents get word from HQ that an enemy spy is on their trail, there is no other option for Joe and Sam except to put their differences aside and work together to solve the case.
