The arrival of David Rice (Robert De Niro), a well-meaning but emotionally complex man, disrupts Rachel’s tightly held world. David, drawn to Link’s innocence, becomes a catalyst for the son’s awakening. When Link, curious and kind-hearted, forms an affectionate bond with a young woman named Carol, Rachel’s panic surfaces. To her, David’s influence and Link’s growing autonomy are threats—a challenge to her role as caretaker and a reminder of her son’s vulnerability in a world she cannot fully guard.
