Inspector Blunder

In post-war France, Inspector Jules Clément is fatally wounded by Pierrot le fou. On his deathbed, he tells his young son Michel: 'You’ll be a cop, my son!' His words plant the seed of Michel's future career.

Years later, Michel grows up under pressure from his mother and yearns to fulfill his father's dream. He commits to the police path and begins pursuing a career as a police officer.

Michel, a hopeless student at the Police Academy, manages to pass the inspector exam thanks to a special jury indulgence. He then becomes a judicial police trainee at the Paris Police Prefecture.

On his first day as a trainee, Michel is beaten by fellow officers who mistake him for an associate of the public enemy Morzini. Marie-Anne Prossant photographs the incident and threatens to publish unless she is allowed to cover the police.

Marie-Anne is assigned to Michel's team along with veteran officer Watrin. She pursues an exclusive angle on the police's activities and becomes involved with Michel.

The public face of Morzini becomes a mystery as he undergoes cosmetic surgery to adopt a new look similar to actor Gérard Depardieu. This disguise is intended to escape police attention.

Morzini threatens Marie-Anne over the phone, and Michel is assigned to protect her. The job is a distraction; more experienced officers monitor them while the plan to capture Morzini unfolds.

Under the pretense of seeking advice, Morzini befriends Michel and learns about the police's inner workings. Michel, naïve to Morzini's true intent, reveals critical details about their plan.

Morzini kidnaps Marie-Anne and demands a ransom from her father. Michel is arrested by his colleagues who suspect him of colluding with Morzini.

His colleagues plant a tracking device in Michel's jacket and release him, hoping he will lead them to Morzini. He soon discovers the device and uses the distraction to pursue the truth.

With the help of some friends, Michel kidnaps Morzini's mother, who reveals the location of Morzini's hideout. This information sets the stage for the final confrontation.

Michel finds the abandoned mansion where Marie-Anne is held hostage and uses an excavator to smash through the building. He rescues Marie-Anne, leaving Morzini trapped on top of the half-demolished structure.

Following the dramatic rescue, Michel and Marie-Anne acknowledge their feelings and decide to face the future together. They phone Marie-Anne's father to report that she is safe, signaling a hopeful new chapter.
