Rebecca grows increasingly concerned that her daughter Lory is not making the right life choices.   The final straw comes when Rebecca learns that Lory has a secret boyfriend, and to prevent any further mistakes, she decides to confine Lory in their basement cellar. What Lory doesn't know is that this is the same cellar where Rebecca was held captive by her abusive father years ago. As Lory battles for survival, the neighbors begin to notice her absence, and Rebecca's behavior draws suspicion, making her a prime suspect in her daughter's disappearance. Haunted by her traumatic past, Rebecca grapples with her actions and the conflicting feelings of guilt and justification over what she has done.
