Newspaper reporter Pete (Bing Crosby) works in a Paris orphanage. His charming way with children and music enables him to find homes for even the most troubled kids. One afternoon, Mr. and Mrs. Godfrey (Alan Reed and Minna Gombell), an American couple, come to the orphanage to adopt Bobby, a boy they saw in one of the ads Pete ran in his newspaper. Bobby misbehaves, but when Pete discovers that Mr. Godfrey plays for the Boston Symphony Orchestra, he quickly produces a young blind opera wunderkind, Theresa (Anna Maria Alberghetti), who sings her way into the Godfreys' hearts.
