Top-notch director Shen Jinghan accidentally encounters an old alley and is attracted by screenwriter Song Xiaoxing, who has a handbook and insists on writing about real life - her handbook is full of the late-night lights left at Aunt Liu's wonton stall, the small warmth of Grandpa Lin repairing the radio, and is full of fireworks that have not been diluted by commercial routines. The two worked together to create the movie "The Warm Light in the Old Alley" based on an old alley. However, they encountered plagiarism and rumors in the industry and malicious sabotage by the female supporting actress Jiang Ruoxi. They also witnessed countless new screenwriters being forced to give up their original intentions due to lack of resources.
In order to protect the core of "authentic creation", Shen Jinghan established the "New Screenwriter Support Fund" in the name of Song Xiaoxing. Residents of the old alleys helped: Aunt Liu donated the revenue from the wonton stall, Grandpa Lin contributed old craft experience, and Grandma Zhang became a "story consultant". From film shooting to fund launch, from dealing with industry difficulties to joining hands in official announcements, the relationship between the two became more and more determined as they worked side by side, and the fireworks of the old alley have always been their confidence - there are hot shepherd's purse wontons here late at night, stories of old objects passed down from generation to generation, and a group of people who use goodwill to support the original aspirations of dreamers.
At the end of the story, the movie premiere was filled with applause, the script of the newcomer supported by the fund was completed, and the lanterns of the New Year's Eve party in the old alley reflected the radio ring that Shen Jinghan put on Song Xiaoxing. Finally, the scene is fixed in the wonton shop in the morning light: the two of them are sitting at their desks continuing to write the sequel, Aunt Liu's shouts penetrate the alleys, and the promise of eternal warmth is hidden in every page of the account, every bowl of hot soup, and every life story without falsehood.
