The Promise

- Season 1

(2020)

In the heart of the Landes, during the great storm of 1999, Charlotte Meyer, 11, disappears.

Sarah tries to tie Charlotte Meyer's disappearance to the Fanny Vidal case, convinced Fouquet is responsible for the disappearance of the new victim as well. But as Sarah interrogates the suspect, he tricks her into making an error, jeopardizing her role in the investigation.

Sarah fights to stay on the case, managing to link the two girls' disappearances and piling up evidence against Fouquet. She is troubled when her old high-school boyfriend, Tony, slips back into her life, oblivious to the fact he's a suspect in Charlotte Meyer's murder.

Fouquet has all the trappings of a dangerous child predator. Sarah is sure she's found the man behind Charlotte Meyer's and Fanny Vidal's disappearances. She starts seeing Tony again, unaware that he's been incriminated in her own investigation.

Tony is arrested, but denies having anything to do with the girls' disappearances. Sarah is pulled off the case for being romantically involved with the suspect. Frozen out by her colleagues, Sarah continues investigating the Charlotte Meyer case behind their backs. She discovers an overlooked trace of DNA on the young girl's boots.

The DNA found on Charlotte Meyer's boots leads to a surprising female suspect. Realizing the woman is also involved in Fanny Vidal's disappearance, Sarah moves heaven and earth to find the little girl before she suffers the same fate as little Charlotte.
