Édouard's life is starting to unravel as the awful truth comes out. Benoît makes some startling revelations to Sybille, but she is not entirely surprised. It's not all gloom and doom for her, however, as an old flame is rekindled between them...

Vanessa is coming over to Sybille's house, which is now Benoît's as well. They don't need to spy on each other anymore, but Vanessa is bringing her binoculars anyway. As for Édouard... justice has prevailed.

In part one of "Le Jour où tout a basculé: Nos bébés ont été échangés" (The Day When Everything Changed: Our Babies Were Switched at Birth), a family is in turmoil. Frédéric is very jealous of his wife Anne-Sophie and accuses her of having an affair with an old flame. Although all the evidence seems plausible, is there another explanation?

Anne-Sophie and Frédéric are at loggerheads and won't speak to each other due to the unexpected results of a paternity test. Anne-Sophie receives some news at the end of the video that suggests the situation will become even more complicated.

Anne-Sophie meets with Fred to tell him the bombshell news about the paternity test results. Will this bring him back home?

The private detective's investigation reveals that Frédéric and Anne-Sophie's daughter Manon was switched at birth with another baby. They are distraught and can't face telling Manon the truth.

Frédéric and Anne-Sophie meet Manon's biological mother Laetitia in a café under the pretext of a survey. Totally unsuspecting, she is in shock when she finds out the real reason for their visit.

While Anne-Sophie and Frédéric have a meeting with Manon's biological mother, Manon carries out her own investigation and finds the detective's report. By the time her parents come home, she's gone, and panic sets in when Frédéric discovers her farewell note.
