Captain Philippe Boulier, called 'Le Squale' (The Shark) (Jean Reno), is monitoring the actions of Augusto Zargas (André Schmit), a former Argentinian colonel and current arms dealer.

To track his movements, the French secret service (DGSE) hides a microphone in the engagement ring of Marie-Laurence Granianski (Valérie Lemercier), an interpreter for the consul general, one of Zargas' associates (Marc de Jonge).

'Le Squale' tries to sabotage the couple's relationship by tempting the husband with a beautiful woman, so that Ms. Granianski will cancel her wedding anniversary and remain at the consulate.

Other actors were considered, such as Daniel Auteuil (who was shooting the film Lacenaire), Thierry Lhermitte, Gérard Lanvin, Pierre Arditi,[7] and Bernard Giraudeau.

To represent the President of the Republic, a character only seen from behind in the film, a "casting of skulls" was made to find an actor whose head looked closest to that of François Mitterrand.

Initially, the scenes taking place aboard the Citroën BX had to be made on a voiture travelling, a common filming technique where the actor pretends to drive the vehicle.

Jean Reno himself made the decision to actually drive the BX 140 km/h on the national, among the flow of normal traffic, with a remote camera attached to the hood of the car and the sound recording equipment installed in the trunk.

The film honors the Citroën range of the moment, where several contemporary models of the brand appear throughout this comedy (AX, BX, XM, CX EVASION Ambulance, C 25).

The Saviem SM 7 truck of occupational medicine, which acts as a "submarine" for DGSE agents, is parked in front of 74 avenue d'Iéna at Paris, in the 16th arrondissement, near the Arc de Triomphe.

On his arrival to visit his wife Marie-Laurence (Valérie Lemercier) at the Consulate, Jean-Jacques Granianski (Christian Clavier) parks his Citroën BX in front of 74 avenue de Jena.

The scenes where the Citroën BX rolls on the national road with Jean Reno and Christian Clavier on board take place on Route nationale 12 between the villages of Cherisy and Houdan.

The scenes taking place at the home of the Granianski are supposed to happen at Dreux, at the fictional address "24 avenue du Paris, residence Pompadour".

When Le Squale (Jean Reno) and Aspirant Garcia (Mireille Rufel) return to Paris after the explosion of the Granianski BX, and after abandoning it in the middle of the countryside, they park the SEAT Marbella level 41 avenue George V, at the time before Bank Hervé (now replaced by an Armani store).
