She had an illegitimate child and with the earnings from her millinery shop, she has sent him away to be educated. When Don, her son (Arnold Gregg), returns from college, he finds he has to defend his mother constantly. He is accused of murdering a man who made a snide remark about Aurora and is put on trial.
