The Promise (Season 1)

"The Promise" (La Promesse, 2021) is a French crime drama you can watch online on iFILM. The morning after Christmas 1999, eleven-year-old Charlotte Meyer vanishes from a small town — no trace, no witnesses. Police captain Pierre Castaing takes the case and can't close it. The investigation outlasts his marriage and his peace of mind.

Director Laure de Butler runs two parallel timelines: the cold case from 1999 and a fresh disappearance picked up by a younger investigator years later. Olivier Marchal and Sofia Essaïdi lead a cast that keeps the procedural slow and tense rather than flashy. The series works as a portrait of obsession — what an unsolved case does to the detective who couldn't finish it. Stream "The Promise" (2021) on iFILM.
