Alfred spent years as a patient in a mental institution, surrounded by his past. His routine is interrupted when Aristotle, a young new patient with a murky history, is assigned to share his room. Was Aristotle a conscious decision made by his therapist, or perhaps a symptom of Alfred's own illness. Alfred's fears and his reluctance to share his room offer insights into his own past, as well as the past of his young protege, which somehow seems to echo his own. As they become learn about each other and themselves, it becomes increasingly difficult to discern whether these are two distinct individuals brought together by circumstances, or whether Aristotle is simply a ghost of Alfred's turbid past, come to life as part of his treatment.
