In episode 4 of "Cette nuit-là" (2024), the story continues with Sofia receiving a disturbing phone call from her aunt Louise. Sofia rushes to Louise's home and finds her stabbed, lying in a pool of blood. Shortly after, Zoé arrives, having received a message from Louise indicating that Sofia's mother was at her place and seemed unwell, prompting Louise to call the hospital. Zoé discovers Sofia's mother leaning over Louise's body, her hands and clothes covered in blood. Sofia is arrested by the police but is later released by Commander Vandenberg, who doubts her guilt.

Back at Sofia's home, she finds a cryptic message on her bathroom mirror. The message includes a date, a cross, initials of missing persons, and a series of numbers that the police identify as GPS coordinates pointing to Lake Rosweig. Commander Vandenberg notes that the lake is mentioned in Sofia's book "Cette nuit-là," which Sofia admits was a fictional element created with her book club to add dramatic effect.

Sofia insists that the police search Lake Rosweig despite the commander's refusal, as the official investigation focuses on Louise's murder and not the disappearance of Sofia's family in 2001. The commander also cites the high cost of such an operation. However, a local journalist, Arnaud Fresnel, publishes a revealing article that pressures the police to send divers to the lake.

The divers discover the car of Sofia's parents at the bottom of Lake Rosweig. Inside the vehicle, they find the bodies of Sofia's mother and brother, confirming a tragic connection to the long-unsolved disappearance.
