"Mrs. Cass, we were hoping your son could answer a few questions about the girl who disappeared last night..."

Erika Cass enjoys what appears to be an idyllic family life—perfect and serene. However, her world shatters one evening when two detectives arrive unannounced at her doorstep.

In the peaceful suburbs where Erika resides, a high school girl has gone missing, and the police harbor grim suspicions of foul play, possibly murder. To complicate matters, Erika's teenage son, Liam, emerges as the last known person to have seen the girl alive.

Despite the facade of perfection, Erika has always harbored a sense of darkness and disturbance around her seemingly flawless elder child. Desperately wanting to believe in Liam's innocence, she finds herself grappling with an increasing pile of evidence that suggests he may have committed the unimaginable.

Now faced with a gut-wrenching dilemma, Erika must confront the burning questions:

How far is she willing to go to shield her son from the ominous truth?
