Zhang Yamei (Di Ying), the first wife, is a troublemaker. Fortunately, Jojo's mother, Li Tie (Liu Ruiqi), is a very smart person. She has many ways to solve various family problems and is called "Iron Mother". When Joe was a child, she was trapped in the ruins by a big earthquake. Fortunately, a teenager saved her. Joe was deeply impressed by the boy and hoped to see him again one day.

Many years later, Hilda came back from abroad and graduated with first-class honors. Despite her father's opposition, she resolutely joined her sister Hai Hanzi (Lin Ketong)' s police academy. Joe met the instructor (Johnny Lu) at the police academy. Cang is smart and fierce, and he can sacrifice his future for justice. To Joe's surprise, Cang turned out to be the teenager who saved himself.

However, Takakura was shot and left an indelible bullet in his body. The bullet kept releasing lead poison, slowly eating away at his life. Cang was shot indirectly by his boss Lin Qiushui (Fan Guangyao). Qiu Shui is a despicable senior police officer, who is best at taking the credit of his subordinates for himself.

In order to uphold justice, Gao Cang led Hilda, Man, (Lin Youwei) and other team members, who constantly clashed with Qiu Shui at home, but openly challenged dignitaries abroad, and finally cracked many major cases that caused a sensation in Taiwan Province Province, including "serial killer case" and "Sargam rape case" ... In this process, Hilda and Takakura supported each other and their feelings grew day by day.

However, Takakura's life is coming to an end. In the last days, Hilda and Takakura knew each other and fell in love, and continued to fight criminals. One of the biggest enemies is Takakura's good brother for many years and the newly rising gangster "Brother Miao".

Actually, Brother Miao (Wang Chuanyi) is not a senior in the underworld, just because he is bad enough, cruel enough and awesome enough, even a senior corner brother won't mess with him, because this person won't mess with you.

The more beautiful Taiwan Province Province is, the happier people are, and the more depraved they are. How do dying Takakura and Hilda fight criminals to the end?
