Jessica ChastainandAnne Hathawayplay a pair of neighbors whose bond is tested in the wake of a personal tragedy in their new movieMothers' Instinct.

Studio Canal UK released the trailer for the film on Tuesday, showcasing real-life friends Chastain, 46, and Hathaway, 41, as Alice and Celine, respectively.

Chastain’s character Alice is shown confiding in Celine her fears that she is a “terrible mother,” some time before she witnesses a tragic accident: Celine’s son Max falls from the family’s second-story porch to his death, leaving both women’s families grieving.

Alice’s initial attempts to comfort Celine in the wake of Max’s death goes poorly, and Alice seems to grow concerned with her son Theo’s own relationship with Celine. Grief appears to impact both women profoundly, and Alice’s own husband accuses her of losing her grasp on reality as she grows fearful that Celine intends to harm Theo.

“Of course it’s a different kind of film, but it’s this idea of these two actresses coming together and playing this…the tension I think is very interesting," Chastain told the outlet. “Thank God Annie and I love each other, so it’s a little different than that experience.”
