A local festival in Mangjin suddenly changed from the Jeongjong Cultural Festival to the Yeonsan-gun Cultural Festival a week before the event. Hye Soo, the representative of a startup, struggles to keep the festival going smoothly. However, Sang Min, co-representative of Moeum-man, brings Rae Oh, a former employee, to the part-time job. On the day of the festival, Eun Chae, an intern picked locally, is overly enthusiastic. To make matters worse, right before the festivities begin, the seats are empty, the guest singers are flat, and the local theater company declares a boycott... The killer festival where nothing goes their way.
