Stan is trapped. His mind, straining under the pressure of advanced Alzheimer's, has penned him into a world where so little makes sense, and where life is a daily puzzle that teases him with its demands and illusions. His caregiver struggles to find and preserve what few links he still has with reality, but despite her efforts only two clear thoughts pulse in his mind: the need to remember a forgotten line of poetry, and the need to find a certain green cardigan. These missing items dog him obsessively, day after day, until one Fall night he follows their ghostly trail into the cold. This is where his journey ends: an ecstatic reunion for him and his departed wife, and a final departure from the lonely world he leaves behind.
