It's about a jewel-encrusted woman who asks Kogoro to be her personal bodyguard. Just then, a man named Mr. Pusheng called and asked Kogoro to help him find an alibi for the murder of Mr. Yi, an ancient art dealer. Kogoro accepted the entrustment and declined the woman. On the second day after the meeting, Kogoro began to investigate every day, and every night Pusheng would come to urge the phone. It was not until Friday night on the sixth day that Pusheng called and said that he was "desperate". The next day, Pusheng's body was found in the Woods. . . . .

Five years ago, Pusheng was mistakenly arrested by Wu Gang, a classmate of Xiaowulang Police Academy, so Pusheng's nephew insisted that Pusheng committed suicide, and later called to say that the criminal who killed Yi Lirong had been caught. And Maori judged it was homicide according to the environment.

At Pusheng's home, I learned that Pusheng's nephew was refused to borrow money, and there was a contradiction with Pusheng. Later, one of the reporters who interviewed Kogoro actually knew the inside story of the case. Wu Xiang came to Xiaowulang's house, and Xiaowulang learned that Wu Xiang also bore a grudge against Pusheng, but Wu Xiang had a perfect alibi when he committed the crime. The woman who sells jewelry seems to have something to do with this case.

Pusheng's nephew was drunk and said, "When Pusheng dies, the inheritance will be mine", which was also suspected by Kogoro. Kogoro and Wu Xiang learned from their memories that it was their nephew who revealed the news, so they went to find his nephew and found his nephew hanging his body in his new well. And Kogoro began to realize that Noi was forced to death because of his own doubts. So he calmly faced the interview in his memory, and there was a "closed day". . . . . .

Conan realized that the prisoner's purpose was to frame Kogoro, and Xiaolan called Yingli to cheer Kogoro up. At this time, the jeweler just took Kogoro away as a "bodyguard", and Yingli was angry. In the hospital, Kogoro heard that Pusheng had been checked the day before the appointment, and he controlled his diet, but on the day of meeting, Pusheng ate a lot, so Kogoro and Conan realized the prisoner's tactics and ran to the restaurant where they met. The two men went to inquire about the recording of Pusheng again and found the recording tape of Pusheng's speech, while Kogoro was attacked on the road and was robbed of the tape. Conan remembered that Happy Bread had been complained, and went there with Kogoro to find the recording. They know the crime, but they don't know the real purpose of the murderer. Xiaowulang suspected that the biscuits on the wall might be made by Wu Xiang, and went to investigate the matter five years ago. He learned that Pusheng and his nephew attacked Dai Rong five years ago, and then a witness testified against them and arrested Pusheng, but the witness proved that Pusheng's alibi was wrong. This witness is Wu Gang's wife.

Kogoro pretended to be drunk and asked Wu Xiang to see him the next day.

Before the beach, Kogoro talked about the criminal's modus operandi, pointing out that Pusheng, who had been seeing and hearing all the time, was a fake criminal, and pointed out that Wu Gang was the criminal. Wu Gang admitted that everything was because he and his wife who had just died "caught the truth by mistake" and then tried to escape and jump into the sea. With the help of Conan and Kogoro, he stopped the incident.
