Jiang Yuanlan, an expert on historical records, once dreamed back to the Anti-Alliance secret camp in 1938 in the archives room. From "talking about war on paper" to experiencing the war in person, he has a known ending in his hands, but has to face the unknown human heart. In Jiamusi, the hot land of "Little Yan'an in Northeast China", he is both a witness to history and an observer of human nature. With one stroke of paper, he not only recorded the heroic songs among the white mountains and black waters, but also connected the fate of a group of little people. When the torrent of history hits his face, the only thing he can do is to leave a warm name for those heroes who are destined to be unknown.
