M17 is being targeted by a massive cyber attack from South of France, exposing the identities of all its current field agents. As a result, M17 is forced to reinstate older inactive agents in order to track down the culprits behind the attack. Among the reinstated agents is Johnny English, who officially works as a geography teacher while secretly training his young students in espionage. After accidentally incapacitating the other agents, English insists on being given the services of his old sidekick, Bough, who is still a clerk in M17.
