He knows no fear. He knows no danger. He knows nothing.

A lowly pencil pusher working for MI7, Johnny English is suddenly promoted to super spy after Agent One is assassinated and every other agent is blown up at his funeral. When a billionaire entrepreneur sponsors the exhibition of the Crown Jewels—and the valuable gems disappear on the opening night and on English's watch—the newly-designated agent must jump into action to find the thief and recover the missing gems.
