Pao and Sheung Sheung reports to the Emperor about their findings. It turns out the mochi that contains peanuts is made by Consort Yin. She is called forth but she denies putting peanut in the mochi.
Guards are sent to Consort Yin’s room to search for any peanuts. An eunuch finds a box which contains a doll with the Prince’s birthday on it and it is stabbed by a needle.*chinese believe that if you have the doll with a person’s birthday on it, whatever you do to the doll will also do on the actual person* Consort Yin is sent to prison.
The guards search the room further and find a box of peanuts. The Emperor is furious but he tells Pao to investigate more about it first. Sheung Sheung is talking to the Princess at the back garden. The Princess doesn’t think Consort Yin is the culprit and thinks that someone is trying to get her.
Pao interrogates Consort Yin at the court but she denies all charges. Kai On tells Pao to punish her since all the evidence is here but Pao doesn’t think the evidence is solid enough. He decides to postpone it in a later date.
When Pao is reviewing the evidence, he discovers that the a box that contains peanuts is very big. He goes to Sheung Sheung for an experiment. He tells her to open the box with one hand and she can’t do it because her hands are too small. They realise that the person who put the box in Consort Yin’s room is a man and now it reinforces their idea od Consort Yin being innocent.
The Princess wants to prove Consort Yin’s innocent by sneaking “evidence” into another Consort’s room. She wants to prove how easy it is to frame someone in the palace. However, she can’t get over the tall walls so she calls Chin Chiu for help. Chin Chiu refuses but the Princess threatens him so he has no choice. Unfortunately, the Princess is too clumsy and she is soon discovered by the Emperor.
Pao and Sheung Sheung tells the Emperor about their suspicion and an eunuch suggested an suspect. The suspect is a guard who has rumored to be Consort Yin’s secret lover. The guard is brought forward and he admits having private meetings with Consort Yin but he claims that it was only for business. An eunuch comes and tells the Emperor that he has found a handkerchief under the guard’s pillow. The handkerchief belongs to Connsort Yin. The Emperor orders Pao to investigate this matter.
In the court, Pao asks Consort Yin if she has a love affair with the guard. She tells him that they are only on good terms because they are from the same hometown. However, her maid and eunuch testify against her. One says that they were cuddling and the other says that the guard went into Consort Yin’s room for a long time and never came out.
Consort Yin swears that she never committed adultery and that whenever she meets up with the guard, it is always in broad daylight and with lots of people. She doesn’t get why her maid is lying. Kai On says that she must be executed but Pao says there’s more to this case. Kai On uses the Emperor as an excuse and tells Pao to punish her unless he wants to be considered as a accomplice. PAo is not taking any of this and tells him do shush his sh!t cuz he will explain it to the Emperor on his own.
Consort Yin knows that she is no way getting out of this so she asks Pao for two favors. One is to see her father and the other is to see her son. The first one is not possible because she was separated from her father a long time ago so she wants Pao to make sure her second wish come true. However, Pao is in a difficult situation since her son is the second Prince and now that the Crown Prince died, he is the Crown Prince. Pao isn’t giving up at all though, he is thinking of beseeching the Emperor.
Adviser Gongsun brings an enormous meal to Consort Yin. He comforts her and drinks with her. Consort Yin drinks until she passes out. The Emperor refuses to meet Pao so he can’t asks him to let Consort Yin meet with the Prince. Pao and Sheung Sheung thinks that it is Kai On’s doing. Pao suggests kidnapping the Prince to Consort Yin but Sheung Sheung dismiss the idea almost immediately.
Sheung Sheung brings the Prince to Consort Yin by herself because she doesn’t want to get PAo in trouble. Pao finds out about it few minutes after and is disappointed that Sheung Sheung acts without him.
The prison is on fire and Pao discovers that Consort Yin is missing. It turns out Adviser Gongsun is the one who helped her escape . She leaves in a boat. Pao knows that the fire is just a facade and that someone plans this all along to get Consort Yin out of prison. Just when he orders his guards to search for anyone suspicious, Adviser Gongsun arrives and admits to be the one who helped Consort Yin escape.
Pao thinks there must be some reason for him to do that and pleads him to tell the truth. Adviser Gongsun just tells Pao to punish him. In the court, it is time for judging Consort Yin’s case and Kai On urges him to call forward the criminal. Instead, Adeviser Gongsun walks in. The Princess, Sheung Sheung and Kai On are shocked.
Adviser Gongsun reveals that Consort Yin is his long lost daughter so that’s why he freed her. He tells everyone about what happened as people didn’t know he has a daughter. He explains that he knows that Consort Yin is his daughter because she has a tattoo on her shoulder which he tattooed himself when she was young. Kai On doesn’t care and thinks that Adviser Gongsun should still be beheaded. However, Consort Yin appears this moment and begs Pao to not kill her father.
Kai is arguing with PAo- he tells him if he doesn’t punish the two now, he will be condered a accomplice as well.Pao tells him tht even if he is, it’s none of Kai On’s business cuz it’s the Emperor that determines Pao’s life and death. Adviser doesn’t want Pao to be dragged into his mess so he tells Pao to punish him. Consort Yin begs Pao to forgive Adviser since she came back. She then bids her father farewell and commits suicide.
