Before his death, Don Pepe instructs Delfin to continue his noble deeds and pass this on to his daughter.
Anita becomes more enraged when she sees her name in newspaper losing heavily in gambling. She castigates her editor, but the more Anita berates him, the more Delfin teaches her the social value of clean living.
