At night, A Chun (Tanaka Silk Dai), a prostitute in her fifties, roams the streets. After walking into a temple, she recalls her rough and miserable first half of life. When he was young, A Chun was a maid in an aristocratic family. She fell in love with the inferior samurai Shengsuke, and the two were found having an affair. Ah Chun, together with her parents, was expelled from the city, and Shengzhosuke was executed. In order to inherit the incense, Lord Songping sent people everywhere to choose concubines. The beautiful Ah Chun was chosen to be the concubine of Lord Songping. Soon, she gave birth to a son. The Songping family was overjoyed, and Ah Chun thought he had settled down. But the original wife was very jealous of Ah Chun, so the Songping family sent her home on the grounds that A Chun had confused the lord. In order to repay the debt, A Chun's father sold her to a brothel. A high-spending guest took a fancy to Ah Chun and wanted to redeem her. However, this man is a liar who specializes in counterfeiting money, and then he is taken away, and Ah Chun is also driven away by the brothel. After that, A Chun went through all kinds of twists and turns, and she finally had no choice but to fall into the street. When she was sick and poor, she learned that her son had become a lord.
