"Brave Heart" tells the legendary life of Huo Xiaolin, a generation of chivalrous doctor who rose from a cowardly young man to an anti-Japanese hero during the warlord war. Bearing the hatred of his family and the country, he endured the humiliation and heavy burden in Songjiazhai, and finally formed a volunteer army to fight against the Japanese invasion with a "brave heart", composing a heart-stirring anti-war epic of a grassroots hero.
