Who has been seen at two of the crime scenes?
Johnny English is a kindhearted but inept MI7 secret agent with dreams of being their most trusted employee. After Agent One dies in a submarine accident unknowingly caused by English, the remaining agents are assassinated via a bombing at Agent One's funeral, leaving English as the lone surviving agent capable of finishing the mission Agent One left when he died. 
English is assigned to thwart a plot to steal the Crown Jewels, which are on display at the Tower of London. During the display, the power suddenly suffers a blackout and the jewels are stolen. During the chaos, English accidentally knocks out the deputy head of security and pretends to fight an assailant to make up for his mistakes.
He later makes up a false description of the "assailant" to MI7 head Pegasus. English and his assistant Angus Bough find that the jewels were removed via a hole dug beneath their display case. The two follow a tunnel where they confront the two thieves Dieter Klein and Klaus Vendetta, who escape in a hearse, with English trying to pursue them but he mistakes another hearse for the escaped vehicle to which he accidentally gatecrashes a funeral until Bough comes to his aid by pretending English is an escaped mental patient.
English connects the thieves to Pascal Sauvage, a French prison entrepreneur who helped restore the Crown Jewels. Pegasus finds the claims of his involvement absurd and warns English not to involve Sauvage. In the car park, English and Bough are attacked by Vendetta but are unharmed. English again encounters Lorna in a sushi restaurant as he recognized her pink motorcycle.
During their meeting, English is suspicious of her since he has seen her at two of their crime scenes and her records cannot be found on any government computer. English and Bough then decide to break into Sauvage's headquarters via parachutes, but English mistakenly lands on a visually identical tower which turns out to be the City Hospital.
