Lin Mu, the logistics supervisor at Hongyuan Garment Factory, is eating at Zhang's Fast Food Restaurant when he asks for a spoonful of braising sauce and is charged an extra three yuan by the owner, Liu Cuilan, who also insults him. Lin Mu decisively breaks Zhang's exclusive catering privilege and brings in Zhao's Stir-Fry, a restaurant offering good-quality food at affordable prices and operating honestly. After losing customers, Liu Cuilan refuses to reflect on her behavior. Instead, in an attempt to win customers back with rock-bottom prices, she betrays her conscience by using inferior frozen meat made from lymphatic tissue and chemical flavorings to prepare her dishes. Eventually, angry diners expose the substandard food on the spot and overturn their plates. Liu Cuilan ultimately smashes the livelihood she has spent nine years building with her own hands.
