This drama tells the historical story of how Mao Zedong, a young man who returned from the First National Congress of the Communist Party of China from 1921 to 1927, grew from a follower to a pioneer and trailblazer in the process of practicing the Marxist faith with the attitude of a "pathfinder" and "early walker" and explored the correct path of the Chinese revolution. From developing league members and party members to launching the workers' movement, from the first cooperation between the Kuomintang and the Communist Party to resolutely fighting against the right-wing Kuomintang, until walking into the fields and measuring the significance of the peasant movement to the Chinese revolution with his footsteps, the young Mao Zedong always adhered to the essence of Marxism and Hunan culture, grew up, took root, dared to be the first, and integrated knowledge and action. "Ask the vast land, who is the master of the rise and fall?" It was the long questioning and exploration of the young Mao Zedong and his companions that opened up a vast new world for the Chinese revolution.
