Summary
A former student (Jake Gyllenhaal) of a recently deceased, brilliant mathematician (Anthony Hopkins) finds a notebook in his office containing a proof of an important theorem, but the mathematician's 27-year-old daughter (Gwyneth Paltrow) claims it is hers. The ensuing dispute is complicated by a burgeoning romance and signs that she may have inherited her father's mental illness.
