After taking over the construction team his father left behind, Lin Yuan's first priority is to solve the workers' food problems. Liu Hong, owner of Hongyun Catering, has relied on his connections and status after ten years of cooperation, increasingly neglecting the workers. When Lin Yuan suggests changing the canteen provider, Liu Hong mocks him, convinced that the young team leader cannot do without him. Determined to ensure his brothers get a proper hot meal, Lin Yuan approaches Zhang Cheng, an unassuming lunch-box vendor. One small food stall and one ordinary boxed meal are enough to restore the workers' trust and motivation. What Liu Hong never expected was that the little stall he looked down on would gradually take away his business.
