A Shi, an orphan in Blue Stone Alley, guards the herbal tea stall left by his father. Unwilling to hand over the alley entrance land, he matches wits and courage with Lord Zhao, who wants to seize Blue Stone Alley. With the help of the grey-robed Granny and old neighbors, A Shi sees through fake land deeds, guards the old roots of the incense shop, learns the art of blending incense, and rallies the hearts of everyone in the whole alley with a sincere original heart, ultimately making the incense of Blue Stone Alley flourish again and generations turn toward kindness.
