Jason brings his girlfriend Claire home for the first time. His mother Sarah, a prison officer with twenty years' experience, senses something deeply wrong: Claire sits rigid and guarded, flinches at loud noises, and answers questions about her past with vague generalities and no real memories. The family sets a trap to test her; instead of answering plainly, she fishes for clues to build rehearsed lies. On the drive home, she eerily names the prison Sarah once worked at, then gives Jason a cross and coldly asks if he would hate her for lying. Using a discounted health check as bait, Jason obtains her ID details. The records check out—yet the photo on file is not the woman before him. The real Claire Morgan has been missing for five years. Just as the truth surfaces, the mysterious Claire appears silently behind Jason.
