A bit higher-budgeted than most of Universal's "pocket" musicals, Get Hep to Love runs a full 79 mintues rather than the standard hard-and-fast hour. Gloria Jean plays child musical prodigy Doris Stanley, who is overworked and exploited by her avaricious Aunt Addie (Nana Bryant). Escaping her aunt's clutches for a well-deserved vacation, Doris manages to elude the private detective (Tim Ryan) hired to bring her back. Landing in a small town, she assumes a phony name and allows herself to be adopted by young marrieds Stephen and Ann Winters (Robert Paige, Jane Frazee). She also attends a "normal" high school for the first time in her life, where she vies with brattish Elaine Sterling (Cora Sue Collins) over the affections of Jimmy Arnold (Donald O'Connor). In standard movie-musical fashion, everyone's problems are straightened out with a climactic production number, spotlighting Gloria Jean's operatic soprano and Donald O'Connor's fancy footwork.
