Lin Weidong, a village chef, remains true to his principles in cooking. He uses honest, quality ingredients and upholds professional integrity, preferring to earn less rather than deceive his customers. To save money, village Party secretary Ma Baowang hires Wang Biao, a food vendor, at a rock-bottom price to cater his son's wedding banquet, ignoring the well-meaning warnings of others. Wang Biao uses inferior, spoiled meat and industrial seasonings to prepare the feast, leaving guests at the wedding feeling sick one after another. Meanwhile, Lin Weidong selflessly prepares clean, authentic funeral meals at a low price for a poor farming family. His honest craftsmanship earns everyone's respect and brings him major catering orders, demonstrating the simple truth that those in the food business must uphold their principles and put sincerity into their ingredients.
