Alice and Celine are inseparable and share everything, from their daily routines to their secrets. Their perfect harmony is shattered when one of their sons dies in a tragic accident while under Alice’s care. Celine blames Alice for the death of her child and becomes obsessed with protecting her surviving son from any harm. Alice, on the other hand, feels guilty and paranoid that Celine is plotting to harm her and her family. A gripping battle of wills ensues as the two women spiral into madness and violence.
