Female protagonist Lin Xiulian is an independent owner of a local country restaurant in the county town, having seen through human warmth and coolness early on. Her younger brother from the countryside, Lin Weiguo, brings back his girlfriend He Guixiang, who pretends to be gentle on the surface but actually covets the homestead and betrothal gifts to subsidize her younger brother. Lin Xiulian detects the conspiracy and gathers evidence in advance, while He Guixiang teams up with her sister to drug and frame Xiulian's boyfriend. At the family banquet, Xiulian releases the recording to publicly expose the scam, her brother sees the truth clearly and breaks off the engagement, and the greedy scheme ultimately ends up as nothing.
