Johnny English is back! The new adventure begins at a moment when a huge cyber-attack reveals all secret agents of Great Britain, and their boss announces that this is just the beginning of trouble.

Secret services can now only count on him - Johnny English. Recently degraded, he conducts classes at one of the schools. It is then that he is re-appointed to his former position to expose a cunning hacker who threatens the security of the state. But for the mission to succeed, Johnny will have to use all his skills, well, in any case, those he has. The "analog" methods he knows from his youth will have to face the digital technology of tomorrow.
