Celine's son falling

In the trailer, that accident involves Celine's son falling to his death from a balcony — a death that Alice tries to prevent but can't. However, after the incident, a major rift grows between the two friends, with Alice starting to suspect that Celine might blame her for what happened ... and that she might want some revenge. "Guilt, suspicion, and paranoia bleed into their friendship," the plot synopsis continues, "as a psychological battle of wills gives way to a darker side of the maternal instinct." Helmed by cinematographer turned director Benoit Delhomme, "Mother's Instinct" has yet to receive a release date, but the thriller will release in the near future.
