Lyla Novacek (Keri Russell) is a cellist studying at the Juilliard School and living under strict rule of her father (William Sadler). Louis Connelly (Jonathan Rhys Meyers) is the lead singer of "The Connelly Brothers", an Irish rock band. Lyla and Louis meet at a party after their respective concerts, and have a sexual encounter on the rooftop. The day after, they separate in a hurry, and are unable to maintain contact as Lyla is ushered away by her father to Chicago. Lyla is also aware that she is pregnant. Later, when in New York City, after an argument with her father over her unborn child, she is struck by a car. Due to the accident trauma, she gives birth prematurely, and her father secretly puts the baby boy up for adoption under her name, allowing Lyla to believe that her son died. Eleven years later, Evan Taylor (Freddie Highmore) is living in a boys' orphanage outside New York City, where he meets Richard Jeffries (Terrence Howard), a social worker with Child and Family ...

This movie "August Rush" really touched my soul. I was an orphan and identified with this child's yearning and searching for his parents. Near the end of the movie, I started to cry like a baby. "August Rush" touched something tender buried deep inside my soul seventy-six years ago.
My father was killed in a car accident three days before I would have celebrated my third birthday. My father was also Irish and looked a lot like August Rush's father. It was during the Great Depression and my mother gave me up to the county's foster care agency.
I am now seventy-nine years of age. How I yearned down through the years for my parents, especially my Irish father. My mother was French. I met her many years later in New York City when I was in my early twenties. She was cold and rejecting towards me. I could not understand why. I was abandoned a second time by one of my parents.
The movie "August Rush" was healing to my soul wounded since early childhood;and again, in my early twenties. I knew where he was coming from as he longed for his parents. Instead of music, I used my talent of writing to deal with the lost of my parents.
"August Rush" made me fantasize during the movie that my yearning and searching for my parents were like this remarkable child.
