A year ago, Isabelle's life changed forever: someone took her son Mason from his crib while she and her husband slept in the next room. The police found few clues, and so they shelved the case. However, Isabelle cannot find peace; apart from the occasional nap or slipping into a strange state where she loses track of time, she hasn't slept in a year. Her entire being revolves around searching for her son, but she knows she can't live like this. Hoping for a new witness or lead, she agrees to an interview for a true-crime podcast, but the host's strange interest in Isabelle's past unsettles her. His constant probing, combined with her severe insomnia, awakens uncomfortable childhood memories, making her doubt what she remembers from the night Mason disappeared. She begins to question whom she can trust, including herself. Yet she is determined to uncover the truth at any cost.
