Go Mu Chi and Jung Ba Reum Land on a New Case to Solve

The murderer threatened Go Mu Chi (Lee Hee Jun) to kill his brother if he wouldn't do what he wanted. The detective followed him by kneeling on his knees in order to save his brother, but suddenly, the video ended and Go Mu Chi was not at ease.

After the call that they have received from the serial killer during their live broadcast, Detective Go Mu Chi and his team immediately went to the church where his friend, who is a priest, was staying.

When they arrived, they saw the body of the priest, Moon Won (Kim Young Jae), covered in blood and was hanging in the middle of the altar.

Go Mu Chi couldn't believe it. He ran into him, crying, and wanted to hold him. But since it was an investigation, he couldn't do anything but to see Moon Won's demise.

Jung Ba Reum (Lee Sung Gi) was consistent in visiting Go Mu Chi to remind him to take care of himself. After the death of Moon Won, he refused to eat and even went on a leave for work. He was still mourning.

Meanwhile, after hearing that Oh Bong Yi (Park Ju Hyun) was hurt and rushed to the hospital after being attacked by the serial killer, who murdered her grandmother and Moon Won, Jung Ba Reum rushed to the hospital. He was worried about Oh Bong Yi.

When Jung Ba Reum was about to leave, she confessed that she cut the left arm of the killer and it would give him a mark.

After days of mourning, Go Mu Chi started to work again. This time, he became more determined to give his friend justice. He first visited Sung Ji Eun (Kim Jung Nan), to ask some questions about the investigation. She seemed familiar to Go Mu Chi, until he found out that she was the wife of Han Seo Joon, the doctor who murdered his family.
