In the late Qing Dynasty, Xia Yulai, the "ghost-talent" lawyer of Chaoshan who never lost a case, clashes with his daughter, Xia Laibi, who wants to be the Great Qing's first female lawyer, over his unconventional "Summer Fox" methods. As foreign capital invades the Chaoshan market, the father and daughter uncover a sinister conspiracy behind seemingly minor civil and commercial disputes. When Xia Laibi is framed for murder and arson, Xia Yulai defends her in court against corrupt officials and wicked merchants. United, the two rally the Chaoshan locals ("Gagi Nang") for a climactic stand against the foreign threat.

Grandma Ye Shurou from Chaoshan lived a simple life, enjoying her twilight years. Her grandson, Xiaowei, burdened by debt, secretly traveled to Thailand to find his rumored billionaire grandfather, Zheng Musheng. However, Xiaowei returned with shocking news: his grandfather was long gone, and the person with whom Grandma had exchanged love letters was a complete stranger. As Xiaowei investigated, a love affair hidden for half a century suddenly surfaced, striking Grandma's heart.
