Maisy Walters finds a young woman passed out in a ditch next to a sunflower field. She can scarcely believe her eyes when she sees this woman's resemblance to her friend who went missing twenty-four years earlier. However, the lady lying unconscious is around the same age Maisy's friend was when she vanished over two decades ago. Compelled to care for this familiar stranger, Maisy takes her to the hospital, where she lies in a coma. Upon awakening, the woman has no memory of her identity. Feeling bound to her both by moral obligation and curiosity, Maisy offers to let the lady live with her. Maisy decides to call her "Aubrey" after her doppelganger. Aubrey ventures out to a stream behind Maisy's property for evening walks. There, she meets a man named Patrick, whom she is sure she knows, though he insists otherwise. Nevertheless, their connection is undeniable, and they quickly fall for each other. Upon encountering the nearby sunflower field, Aubrey discovers that she has a severe sunflower phobia. Patrick pleads with her to come to his farm for a mysterious urgent reason. Because his farm lies on the other side of the field, she must conquer her fear of sunflowers to reach him and uncover the mystery that will change her life forever.
