Ae-sun (Mun Ye-bong) is the vain wife of a middle-class man who has no interest in looking after her family. Her exasperated husband (Lee Geum-ryong) chases Ae-sun out and she abandons her husband and her daughter Jeong-hee (Yoo Seon-ok) to stay at a hotel with her lover. One day, Ae-sun finds out that her lover is a poor student boarder and a criminal, not the prosperous entrepreneur she thought he was. She reports her lover to the police as he plans to rob someone, and leaves once more to live with a showy dancer.
