One script, two screenwriters, three revisions, four seasons change, five flavors mixed. According to legend, during the early years of the Ming Dynasty, General Chang Yuchun headed north with his army and established a campsite that later became known as "Chang Ying." Several hundred years later, a group of young people also stationed there, dreaming of becoming directors, screenwriters, actors, producers, and more. Among them were two screenwriters, Zhang Liao and Sun Tan. They wrote a movie script that they believed would go down in history and were determined to bring it to the big screen.

Beidiao screenwriter Wei Fei has always dreamed of becoming a pure literature writer, but because of his livelihood, he has no intention of devoting himself to creation. Father Lao Wei came to Beijing to help his son, but he could only make a lot of jokes out of help. The father and son, who hadn't seen each other for many years, gradually understood each other under the brief run-in in Beijing and the encouragement and support of friends, and Wei Fei also retained his persistence in his dream.
