Chen Ye returns to the small town he has been away from for three years, carrying an old travel bag and a bronze key. Facing the old breakfast shop left by his father, he originally only wanted to close the door and leave, but accompanied by Su He, he steps back into that old soup pot. From cleaning the storefront, purchasing ingredients, to studying the taste left by his father, the two gradually recover lost memories. Facing realistic pressures and business difficulties, Chen Ye decides to reignite the fire in three days, using a bowl of hot soup to prove that this shop can still continue, and once again facing his bond with himself and his hometown.
