Lin Zhixia runs an artisanal jam shop in Chunfeng Alley, insisting on using only genuine, high-quality ingredients. However, she receives a notice that the old alley is to be renovated. Gu Yanchuan, the cold-faced man in charge of the project, appears and demands that she create a jam representing Chunfeng Alley within one day. Otherwise, her shop will be turned into a trendy milk tea store. Believing he intends to drive her out, Lin Zhixia enlists her employee Zhou Xiaoman and the warmhearted Granny Chen to create a new jam using neighborhood stories and seasonal fruit. Throughout the day, tastings, failures, arguments, and acts of protection unfold one after another. That evening, she sets up the "Sunny Jam Menu" in the small square and unexpectedly discovers that Gu Yanchuan has actually submitted a plan to preserve the old alley's cozy little shops. Moving from confrontation to standing side by side, the two bring a gentle, unexpected turnaround to the little shop and the entire alley.
