Inspector Warren is puzzled and wants to know more about cross-dressing. So he seeks the office of Dr. Alton, who narrates for him the story of Glen/Glenda. Glen is shown studying women's clothes in a shop window. Dr. Alton points out that men's clothes are dull and restrictive, whereas women can adorn themselves with attractive and comfortable clothing. A flashback scene reveals that a young Glen started out by asking to wear his sister's dress for a Halloween party. And he did, despite his father's protests. But he then continued wearing his sister's clothing, and Sheila (the sister) eventually caught him in the act. She shuns him afterward.
