Lai Muye was saved by Lin's father when he was young. He repeatedly tested and suspected Lin Yiyou, while falling deeply in love with him. He continued to be pulled between good and evil, kindness and heartbeat. However, Lin Yiyou already had Ren Zhiyuan in his heart. On the other side, Lin Yiyou's younger brother Lin Yiyang noticed that his sister was in an unusual whereabouts, and followed online clues to go to the border alone to look for her. The elderly at home and his remarried mother were worried about her day and night, and were filled with pain. In the end, Lin Yiyou relied on forbearance and wisdom to obtain complete evidence of drug trafficking, cooperated with the police to close the network, and captured Lai Muye and the entire criminal gang in one fell swoop.

Ren Zhiyuan and his family finally understood all the forbearance and sacrifice, and all misunderstandings were resolved. After separation and misunderstanding, the two people untied all their knots, the family was reunited, and the perseverance and grievances of the two generations of police officers were finally revealed.
