Nora is a pretty telephone operator engaged to a soldier overseas. On her birthday, she gets a Dear John letter from him. Feeling despondent, she agrees to a date with a wolf from her office.
He gets her drunk and leads her back to his apartment, where she resists his advances and bludgeons him in self-defense. She flees leaving behind the blue gardenia he bought her.
The next morning, she's can't remember the details of what happened.
