1920s Hong Kong was marred by rampant corruption, and Zhang Wang (portrayed by Wan Zhizhiang) took on heavy debts to buy a fireman's position to better his family's life. His selfless actions earned him enemies like Chen Bo (Taidi Zhizhiwei), who plotted to sell Zhang Wang to Southeast Asia. Zhang Wang's wife, Xiu Lan (Miji Xue), embarked on a desperate mission to rescue him, but found herself powerless against the odds.
Zhang Wang was enslaved in an Indonesian mine, constantly attempting escape. He finally met his savior, the boss' daughter Pro Nan (Luo Lin), during one such escape attempts. Pro Nan sympathized with Zhang Wang's plight and helped him establish a transportation business, but their efforts were met with Dutch military suppression, causing casualties among the workers.
Pro Nan fled with her family possessions after the incident, leaving Zhang Wang behind. Pro Nan and Zhang Wang formed a bond during this time, but Zhang Wang's longing for his wife and children never subsided, viewing Pro Nan as a comrade-in-arms rather than a lover.

Zhang Wang continued to yearn for his family, but Xiu Lan found herself torn between duty and affection. Lei Xinghe was willing to let Xiu Lan go but cherished her deeply.
