1920s, corruption runs rampant in Hong Kong. Selfless Long Wang (played by Wan Quanzhang) takes on debt to purchase a firefighter's position, determined to better his family's life. In the process of helping brothers Huang Shui and Huang Shan (portrayed by Lin Jiahua and Lin Wenlong), he angers superior Chen Bo (played by Dai Zhiwei). Chen Bo's friend Zhou Jin Rong (played by Luo Le Lin) plots to sell Long Wang to Southeast Asia. His wife, Yuan Xiu Lan (played by Mi Xue), embarks on a desperate mission to save him, but finds herself in a powerless predicament. Sent to a Indonesian mine as a slave, Long Wang continues to escape, ultimately meeting the owner's daughter Xu Nuo (portrayed by Luo Lin). Realizing the difficulty of his situation, Long Wang decides to wait patiently for his release. Meanwhile, Xu Nuo sympathizes with Long Wang's plight and persuades him to start a transportation business. However, Dutch troops suppress their endeavor, resulting in casualties, including Xu Nuo taking her family's possessions and leaving Indonesia with others.
Moved by Xu Nuo's kindness, Long Wang proposes marriage, only to be turned down. Tragically, Xu Nuo dies, never able to reunite with the one she loved. Tormented by guilt, Yuan Xiu Lan returns to Hong Kong but remains unrecognized by Long Wang. She secretly helps him escape from Huang Shui's relentless pursuit. Despite his chasing, Huang Shui can't let go, causing distress not only for Long Wang but also for his family and wife Little Swallow (played by Gu Ke Yun). In the end, Xu Nuo sacrifices herself to save Long Wang, who, grief-stricken, proposes to her in vain.
Struggling between love and duty, Yuan Xiu Lan finds solace with businessman Lei Xing Hui (played by Wang Wei), who cares for her and their children. Upon reencountering Long Wang in Hong Kong, she hesitates to reveal herself due to guilt. Instead, she secretly aids his escape from Huang Shui's grasp, but he remains unrelenting, causing harm not only to Long Wang but also to Huang Shan and Little Swallow. The story concludes with Xu Nuo's selfless sacrifice, Long Wang's unrequited love for Yuan Xiu Lan, and the lingering consequences of evil actions.
