Lin Wangshu, an apprentice of traditional Chinese medicine, is betrayed by his master, Zhao Shikun, who steals his research achievements and sends him to the remote and impoverished Qinghe Village to work as a barefoot doctor. By a twist of fate, he gains the extraordinary ability to hear the voices of medicinal herbs. Guided by diagnostic clues from the herbs, he repeatedly resolves crises, including obstructed labor, mass drug poisoning, and critical medical emergencies. He confronts the corrupt Zhao family, establishes himself in the countryside to heal the sick, and remains true to his calling as a physician. Ultimately, he exposes his enemies' schemes, clears his name, and finds both professional success and love.
