In England, two weeks before the end of his World War II military service, American soldier and jazz musician Danny Webson Miller is introduced to Jamie Shellgrove, the grandson of the Duke of Dunstable. When the Duke tells Danny that he would like to help his classical musician grandson overcome his shyness and stuffiness, Danny invites Jamie to visit him in Brooklyn. On his first day back in Brooklyn, Danny meets and falls instantly in love with Anne Fielding, a soprano and classical music instructor at the high school he attended as a youth. After re-registering for the draft at the high school, Danny visits his old pal Nick Lombardi, the school janitor, who invites Danny to live with him until he finds an apartment of his own. Unable to audition for work as a musician because he suffers from stage fright, Danny soon loses confidence in himself and concludes that he will only be able to get work as a shipping clerk. Meanwhile, Anne tries to encourage a talented young pianist, Leo Kardos, to pursue a career in music, but Leo tells her that his mother cannot afford to pay for his education. Anne and Nick suggest that Leo seek a scholarship from the Brooklyn Music Forum, but because the boy is too young to qualify for the scholarship, he gives up his dreams and resigns himself to a lifetime of hard work at his mother's candy store. Soon after Jamie arrives in Brooklyn, he moves in with Nick and Danny, and falls in love with Anne. While Danny is busy working at his new job as a song plugger at Mr. Dobson's music store and writing lyrics to one of Jamie's songs, a secret romance blossoms between Jamie and Anne. Jamie's affection for Anne is met with the disapproval of Nick, who has been trying to bring Anne closer to Danny. One day, when Leo's mother tells Danny, Jamie and Anne that she is ashamed that she cannot provide her talented son with the money he needs for music lessons, the friends suggest that Leo raise money himself by giving a concert at Dobson's music store. Following the concert, the scholarship committee, impressed with Leo's talent, makes a special consideration for the boy and awards him the scholarship he sought. A short time later, Danny, realizing that Anne and Jamie are in love, graciously gives his blessing for their romance, and decides to pursue a romance with a nurse he met in the army.
