Eun Sol, a newbie prosecutor, holds hands with Baek Beom and Cha Soo Ho to investigate a murder case of a conglomerate’s son’s wife. Sol and Beom specu-lates that the husband beat her, who was pregnant, to death. However, Beom tells her never to trust the corpse itself because once a body decomposes, new scars may show up, and existing wounds may vanish.

Eun Sol is shocked to see Baek Beom stand as a witness for the conglomerate son, Oh Man Sang. Beom testifies that the cause of Kwon Hee Kyung’s death is not assault. Meanwhile, due to the lack of evidence, the trial is postponed for three days. Will Sol be able to find more evidence to prove that Man Sang is the killer, or will Man Sang be set free?

Although the trial seems to be leaning in the defendant’s favor, Sol does not lose heart and begs Beom to analyze the heels that she wore to the crime sce-ne. The results show that on the carpet where Hee Kyung was found, traces of pills are found. Sol immediately believes that Man Sang has replaced the con-tents of Hee Kyung’s pills into those that would kill her.

Sol goes on her 99th blind date and is not impressed with the low self-esteemed mama’s boy. To his mother who has been watching them the entire date and has handed her three million dollars in order to convince her to marry him, Sol tells her that her son should learn how to grow his self-esteem and figure out his own life. Meanwhile, Deuk Nam’s three sisters find out that their brother’s body is missing and goes berserk.

Suspecting the late Jang Deuk Nam’s death to be a murder case, Sol indicts his three sisters and his wife, Choi Hwa Ja, for murder. Meanwhile, while talking with Kang Hyun regarding the murder case, Hyun tells Sol not to trust Baek Beom too much. When she asks him whether there was a conflict between him and Beom, he just warns her to be careful.

Baek Beom finds Choi Hwa Ja’s fingerprints on the dead Byun Soo Kyung’s blouse. He immediately calls Kang Dong Sik to ask where Eun Sol is, only to find out that she has left to meet Hwa Ja. Frantically, Beom calls Sol’s phone. Meanwhile, after waving to Sol and telling her to come in, Hwa Ja mixes an un-known substance in Sol’s drink.

All the wicked deeds that Choi Hwa Ja has done are revealed, and the dead body turns out not to be Jang Deuk Nam. In addition, Hwa Ja had a lover on the side, and the corpse belongs to that man. It is revealed that Hwa Ja murdered both of the men all because of the inheritance. Despite the result claiming that Hwa Ja’s kid is actually Deuk Nam’s and not her lover’s, Sol requests a heavy verdict.

Soo Ho’s shoe is found at the house of Yeon Mi Rae, who has been found dead. Sol and Dong Sik immediately go to his place to find him reeking of alco-hol. Soo Ho is taken to the police station as a suspect. When Dong Sik asks him what happened last night, Soo Ho tells him that he cannot remember.

All the evidence that they find point toward Soo Ho. Although he cannot re-member much from the night before, he implores that he did not kill Yeon Mi Rae. Due to Sol’s relationship with Soo Ho, Kang Hyun is appointed as the lead prosecutor for the case, and Sol is only allowed to work with him. Although she cannot find any sturdy evidence that can help Soo Ho, she feels it in her stomach that he is not the murderer.
