Two months before the lake incident, Margot learns that Philippe Neuville has been sexually abusing children from a trust. She seeks a confession, but the confrontation quickly turns dangerous. The discovery sets off a plan to protect Margot.

During an attempt to secure a confession, Philippe attacks Margot, leaving her battered and shaken. The assault underscores the peril surrounding her investigation. The event marks a turning point for Margot and her father.

To protect Margot, her father shoots Philippe after witnessing the attack. This act transitions him from protector to covert mastermind. The incident triggers a long, hidden campaign to shield Margot.

Fearing retaliation from Gilbert Neuville, Margot's father begins wiretapping Gilbert's phones. He becomes deeply entangled in a web of surveillance and fear. This marks the start of a covert struggle beyond the immediate assault.

Margot's father discovers that Gilbert had hired two men to kill Margot. The danger escalates as he schemes to counter the threat and protect her status and secrecy.

To thwart the assassination plan, Margot's father kills the two hitmen, stages Margot's death using the body of a heroin addict, and sends Margot into hiding. The deception keeps her from public view and buys time. The ruse relies on a complex false narrative.

After the staged death, Margot's father kills himself to avoid arrest, aware that Alex's wire would reveal the truth. The moment leaves many questions unanswered but preserves Margot's safety for now.

Unbeknownst to the police, the father knew Alex wore a wire. He blocks the transmission long enough to confess that Margot shot Philippe. The revelation is designed to protect Margot and preserve the ruse.

Following these events, Gilbert Neuville is arrested for his crimes as the broader cover story begins to unravel. The arrest closes a chapter of the conspiracy.

Eight years after Margot's murder, Alexandre Beck receives an email with security footage that appears to show Margot alive. At the same time, two bodies are discovered buried near the lake where Margot died, and the police start treating Beck as a suspect.

A criminal group monitoring Margot’s emails begins to intimidate Alex's acquaintances. The intimidation escalates to the point that Alex's friend Charlotte is killed, heightening the danger around him.

Law enforcement moves to arrest Alex at the hospital, but he escapes with assistance from Bruno, a gangster who owed him a debt. The escape deepens the mystery and complicates the investigation.

The attempt to reach the park for a scheduled meeting with Margot is interrupted when the criminals abduct Alex. Bruno later rescues him, extending the fragile alliance between them.

The next day, Alex is exonerated after his sister Anne and her wife Helene provide an alibi through their attorney. The alibi shifts the focus away from him and buys him time.

Back with law enforcement, Alex recalls Margot's father's unusual behavior after her death. He confronts the father at his residence, and the truth emerges that Margot herself shot Philippe. The revelations culminate in a heartfelt reunion at the lake where they first fell in love.
