Kinjiro Imai

An old man who has spent his life being respectful, honest and married for 35 years suddenly has thoughts of cheating with a young girl. He goes on a trip with the girl, but they are followed by a yakuza and all hell breaks loose.

Shinichi is not only poor, he is also deaf, and leads a joyless life with his sick mother. His one happiness is his friendship with a girl who works in a bar nearby. Then, one day, his mother dies after drinking the medicine that Shinichi himself gave her. It is discovered that the pills contained poison. He is apprehended on suspicion of murder and taken away for interrogation, unable to defend himself - being deaf and dumb - or even to proclaim his innocence.
