In June 1993, the cross-border cooperation between Donghai Chemical and Luoda Company was in full swing, and Song Yunhui (played by Wang Kai), a key figure in the Donghai joint venture, was leading the workers to carry out process reforms at Pengyang Pesticide Factory, which was inferior to Donghai in all aspects. Song Yunhui, who had experienced a huge gap from Donghai to Pengyang, still adhered to his original intention of struggle. Lei Dongbao (played by Yang Shuo) led Dengfeng Wire Factory to merge small factories and set up Leiting Cable Cluster. He set rules, ran bids, engaged in foreign trade, and attracted investment. He tasted the warmth and coldness of human feelings, but still put the interests of the collective and villagers first. Yang Xun (played by Dong Zijian) and Liang Sishen (played by Yang Caiyu) cooperated to build a shopping mall. Liang Sishen tried his best to balance the interests of Luoda and Donghai in the joint venture, and finally used his withdrawal to restore Donghai to safe production. From avoiding suspicion at the beginning to gradually opening their hearts, Song Yunhui and Liang Sishen communicated with each other and faced the challenges of the future together. All the way ups and downs, the situation is changing, and what remains unchanged is the hard work and struggle of the dreamers who are brave enough to move forward.
