A 5-year-old boy named Yang Yang was alone at home. Due to hunger, he stood on a bench and turned on the gas stove to cook instant noodles. However, due to Yang Yang's young age and improper operation, a natural gas leak occurred, leading to an explosion. Zhang Qixuan, a kind-hearted person from the same community, rushed into the burning room without considering his own danger and took Yang Yang out of a coma. With the help of kind-hearted people from the same community, he dialed 120. Yang Yang's father Zheng Chengguang, who was having an affair with his lover at the hotel, suddenly received a phone call from his wife Wang Yun asking about Yang Yang. Zheng Chengguang made up an excuse for Wang Yun and hurriedly drove home to find Yang Yang. Zheng Chengguang, who was driving to the residential area, saw his disheveled appearance through the rearview mirror and began to tidy up his appearance. At this moment, Zheng Chengguang, who was distracted while driving, collided with the ambulance that was about to leave the residential area. However, the arrogant and domineering Zheng Chengguang did not intend to let go of everyone on the ambulance. With Zhang Qixuan and doctor Chen Shuo's attitude of saving the child first, Zheng Chengguang refused to send an ambulance to the hospital. As a result, the residents decided to spontaneously rescue Zheng Chengguang. The people escorted Zheng Chengguang, and the kind-hearted taxi driver Li Yumei drove Zhang Qixuan, Chen Shuo, Yang Yang and others to the hospital. On the way to the hospital, the insane Zheng Chengguang crazily held onto Li Yumei's car, causing a lot of rescue time to be delayed on the way. Under Li Yumei's superb driving skills, she successfully shook off Zheng Chengguang and took the injured child to the hospital. Everyone anxiously stood outside the rescue room. Unexpectedly, the unreasonable Zheng Chengguang called his wife, Wang Yun, who was rich in beauty, to support him and seek revenge against Zhang Qixuan and others. However, Wang Yun, who had a positive outlook, did not listen to Zheng Chengguang's one-sided words and chose to believe them. He was extremely disappointed with Zheng Chengguang and cursed loudly. At this moment, the little boy was pushed out of the operating room. Due to the delayed delivery time to the hospital, which was only three minutes away, the little boy was declared dead. Under the guidance of the crowd, Zheng Chen quickly opened the white cloth covering Yang Yang. Wang Yun and Zheng Chengguang unexpectedly discovered that the dead little boy was their own son Yang Yang... and it was their biological father Zheng Chengguang who ultimately caused Yang Yang's death...
