Agent Cody Banks (2003)

Nerdy teenager Cody Banks is recruited by the U.S. government and trained for covert operations that call for a younger agent. His assignment puts him back in the middle of ordinary teen life: he must get close to his classmate Natalie to uncover an evil plan connected to her father. But even with spy training and an official mission, Cody still has to deal with nerves, awkwardness, and teenage angst.
