Ben is thrilled to join the Academy of Espionage, which his parents think is a science academy. On his first day, things go wrong as he fails a combat assessment and an assassin tries to kill him. Spy school is harder than Ben expected and he must learn quickly as he gets involved in a plot to uncover a double agent. Though not naturally skilled, Ben starts to improve and earns respect from his classmates by discovering the mole while also developing friendships.
