Keanu Reeves stars as Nelson, a San Francisco ad man who stays just busy enough to keep from noticing his loneliness. But one autumn, Nelson gets involved with a free spirit named Sara (Charlize Theron), who turns his world upside down. Sara, however, insists that their romance can last only one month. Is she afraid of commitment? Or is she hiding a terrible secret? Frank Langella co-stars in this romantic drama from Irish director Pat O'Connor.
