In the spring of 1945, the Anti-Japanese War was about to end, and the Japanese devils wanted to create the illusion of "China and Japan prosper". On the evening of New Year's Eve, they planned to hold a fireworks party in the ancient city. For this reason, the superior instructed the destruction of the fireworks party. This task was handed over to the Xinglong Firecracker House, a long-dorman underground transportation station of the guerrillas. The control of the ancient city must not fall into the hands of the devils.However, before the operation, Wang Xin, the stationmaster and Xinglong Firecracker House apprentice, was betrayed by a traitor and died bravely, which made it very difficult for the character to execute. There was only one rookie trafficker left at the traffic station - Wang Xin's second junior brother, Wildfire.Wildfires usually only set points and whistle people, and this is his ambition. It is really unlikely to complete the "Hironghua Plan": on the one hand, he can hide the investigation of the Japanese military police commander - the cunning, hypocritical, and hard militarist Taishuo Ishihara, and he also has to dispel the relationship between the security captain Jia Ren and the detective captain Jia Yi; on the other hand, when his identity must not be exposed, he deals with his lover Chunfeng and the child bride Doudou, and cannot interfere with this action; at the same time, he also has to appease his junior brother's mentality of avenging his senior brother, and explore the unique skills of the sixth father, the old man in Xinglong Firecrackers House, to make fireworks.Faced with such a dangerous and complex task of the "Hidden Flower Plan", the rookie trafficker Wildfire used his wit to come up with all kinds of strange tricks. This is a seemingly impossible task? And can Chunfeng and Doudou, the love rivals, help Wildfire complete the task at this critical moment? In the end, who will Wildfire choose?
