Cao Xuedong, the former secretary of the Xia County Party Committee in Lin Province, South China, was a sports student. After dying in rescue and disaster relief, he traveled through time and became an unsuccessful actor in the entertainment industry during the 12 years of the Republic of China. In this strange era, he faces the jealousy and suppression of his colleagues in the entertainment industry and the dilemma of low status, but he also carries the secret of the time traveler. On the one hand, his peers secretly sabotage his development opportunities and compete for resources; on the other hand, he wants to break through class restrictions in a short period of time and become a top figure in the entertainment industry. He relied on his handsome appearance and clever words to maneuver in the upper-class wealthy women and entertainment circles. However, emotionally, he fell into entanglements with many wealthy women and actresses, and the lies he fabricated to maintain his image also caused many misunderstandings. In this complex environment, he must gain a foothold within a limited time, otherwise he will be eliminated. As he gets closer to his goal, the secret of the traveler's identity is like a time bomb. Once exposed, he will face pursuit from all parties and emotional collapse. However, Cao Xuedong relied on his modern knowledge and tough character to break through crisis after crisis, and eventually became the legendary social king in the entertainment industry of the Republic of China.
