Hong Sheng (played by Joey Wong) sneaked from the mainland to Hong Kong. She was bullied by the snakehead all the way. She escaped after injuring the snakehead during the fight, but the outside world also made her feel strange and terrified. She initially planned to seek refuge with her aunt, but was rejected by her aunt and ridiculed Hong Sheng, while her uncle coveted her beauty. Hong Sheng had to leave her aunt's house and live on the street again. Inspectors Ho Ting Pong (played by Chow Yun-fat) and Cheung Yan (played by Lu Fang) chased Bai Fenxiong, who drove out of the street and knocked down Hong Sheng on the roadside. After waking up in the hospital, Hong Sheng was afraid that her identity would be exposed and she would be sent back to the mainland. She had an idea and lied that she had a brain injury and amnesia, and she also "identified" that Ho Ting Pong was her husband Weixiong. The kind-hearted Dingbang had to take Hong Sheng back home to live temporarily. The relationship between the two gradually changed, but Hong Sheng's identity as a "smuggler" was like a time bomb in their relationship that existed all the time...
