The theft of the British royal family's jewels caused great tension. The intelligence agency immediately sent out the top agent, "No. 1", to investigate the jewel case. However, before the case was solved, "No. 1" was murdered. At the funeral of "No. 1", the top agents of the British intelligence agency were attacked by a bomb and all died. Soon, the intelligence agency received news that this group of bad guys were planning to attack the British crown. However, the top agents of the intelligence agency were all sacrificed, so they had no choice but to send out a rookie agent, Johnny English (Rowan Atkinson), nicknamed "Agent J". Johnny has neither wisdom nor courage, but he has advanced weapons and the ability of "gossip". Can Johnny finally defend the dignity of the British royal family?
