Victoria meets Nathalie Champigny's brother who is still continuing her research. They try to understand the circumstances of his sister's disappearance. Victoria is also investigating the case of Linda Normandin, who disappeared in September 2015.

Victoria looks back on the months following the disappearance of Nathalie Champigny. She meets up with one of the lawyers involved in the case to discuss a person interviewed at the time.

Victoria analyzes the case of Nathalie Godbout, which seems to be a perfect disappearance. In September 2000, the 26-year-old woman, mother of two children, vanished in the middle of the night, leaving behind all her personal belongings.

The former investigator assigned to Nathalie Godbout's case agrees to confide in Victoria. For Christian Bédard, the suicide hypothesis does not hold water. A former friend of Nathalie Champigny launches Victoria on a new track.

Victoria meets people close to Linda Normandin who allow her to learn more about her. Her daughter, her ex-husband and a former activist against the CSST have the same opinion: her consumption had changed her behavior.

Victoria visits Linda Normandin's ex-husband in prison to talk with him. Gaétan was never a suspect and is incarcerated there for other misdeeds. For Victoria, the hypothesis of “voluntary disappearance” begins to stand out.
