A sudden case caused Zhou Tie's son, a seasoned detective, to suffer serious injuries and become vegetative. His wife was plunged into immense grief and hoped that Zhou Tie could quickly find the person who harmed their son. At this time, his son’s girlfriend, who had always had a good relationship with him and had decided to hold their wedding ceremony in the near future, proposed a breakup.
Zhou Tie's assistant, Li Ding, after divorcing his wife, had been living a single life due to being too busy with work. Their colleague, Liu Dan, had secretly admired this strong man. Seeing Li Ding live such a hard life alone, she wished to get closer to him. But Li Ding seemed completely oblivious to her feelings. As they worked together side by side, Li Ding and Liu Dan grew closer and eventually became husband and wife.
