The trailer depicts the sisterly bond shared between Alice (Chastain) and Celine (Hathaway) as they raise sons of a similar age in the same neighborhood.

But when Alice fails to save Celine's son, Max, from falling off a balcony to his death, guilt and paranoia begin to creep in to their seemingly picture-perfect lives.

“You need to separate the grief from the guilt,” Alice tells Céline, who retorts: “What guilt, Alice?”

What is 'Mothers' Instinct' about?

Based on Barbara Abel’s 2012 novel of the same name, "Mothers' Instinct" was first adapted in 2018 for a Belgian film.

The trailer depicts how the bond the women share begins to deteriorate after Max's death as Celine grows more suspicious of Alice. Alice, in turn becomes more wracked with shame over her failure to protect the boy as she worries that her former friend is out for revenge.

Left without a son, Celine instead grows close to Alice's boy, Theo – further amplifying the growing feelings of mistrust between the once close friends.
