Estranged from his parents by circumstance and nudged toward a foster family, a young boy seeks out his long-lost folks and discovers prodigious musical talent in this family-oriented drama from Disco Pigs director Kirsten Sheridan. In the aftermath of a passionate night together above New York's Washington Square, a charismatic Irish guitarist named Louis (Jonathan Rhys-Meyers) and a reserved cellist named Lyla (Keri Russell) are forced apart by fate. Despite the fact that they do not remain together, however, their fleeting union has created something amazing that neither could have ever anticipated -- a baby. Unfortunately, just after the child's birth, the mother is misinformed that the infant has died. Cut to 11 years later, when the child, Evan, is living in a Gotham-area boys' home and has developed an acute ability to listen to the sounds of the outside world -- hoping against all hope that his biological mother and father will turn up to claim him, while those in charge try to encourage him to open himself up to the possibility of adoption. Unduly rejecting these bids, Evan runs away into the city. Out on the streets, the child falls into the clutches of a manipulative, untrustworthy street person named Wizard (Robin Williams), who renames Evan "August Rush" and opens the boy up to the depth and breadth of his own musical talent even as he smells the opportunity to grow rich off of the foundling. Meanwhile, Evan/August's hope persists that he will be reunited with his folks, and Louis and Lyla, unable to forget their initial night of love, feel themselves being drawn back together by fate.
