The Under-Pup (1939)
The Under-Pup is the 1939 feature film that introduced soprano singing star Gloria Jean to the screen. The story, adapted by Grover Jones from a magazine story by Australian author I. A. R. Wylie, casts Gloria as a streetwise girl who is sent to a summer camp for wealthy girls. She is at first bullied by the other girls, but she stands up for herself and wins everyone over, including the girl who had bullied her the most, to earn a place in their group, "The Purple Order of Penguins".
