Lin Xiaxia is the owner of the Lin Family Bistro on the old street. To protect her family's century-old sign, she resolutely resists the malicious development by the Dingfeng Group. During her most difficult time, the bistro recruits a chopping assistant named Lu Tingye. Lu Tingye is actually a genius culinary god and family heir who suffered psychological trauma and lost his sense of taste, living under an assumed name to rediscover his original aspiration. In the old street full of worldly fireworks, the two transform into comrades-in-arms and fight side by side, not only defeating the opponent's conspiracy with superb culinary skills, but also healing each other through day-and-night companionship. Lin Xiaxia's sincerity awakens Lu Tingye's sense of taste. The two ultimately successfully protect the old street and also reap a sincere love.
