This romantic drama follows the love affair of two people with Asperger's Syndrome -- a subtle form of autism -- as Donald (Josh Hartnett), an emotionally dysfunctional mathematical genius, falls for a musically gifted woman (Radha Mitchell) who also copes with the disorder. Their unique natures, however, make for a challenging relationship. Norwegian director Petter Næss directs this poignant romance inspired by a true story.
