The gleam of a blade cannot rival the warmth of a kitchen fire, and glory is no match for a home-cooked meal. Liu Jinfeng runs a street food stall and took in the down-and-out Ye Qingtian three years ago, much to the ridicule of the villagers. When forced demolition and disputes over compensation erupt, her shop is subjected to water and power cutoffs and constant harassment. Ye Qingtian secretly resolves the crises, and his true identity is finally revealed: he is a legendary security expert who had long since retired. In the end, an old case is overturned, those responsible are punished according to law, and he turns down a high-ranking position, choosing instead to stay at the shop and protect Liu Jinfeng and the entire village, finding happiness in the warmth of everyday life.
