The film mainly tells the story of a brave team composed of BOSS (played by Xie Ming), ECHO (played by Shu Yichen), Ayong (played by Zhang Yong), Qi Miao (played by Zhang Wenjun), and Fatty (played by Duan Xing) in a country in Southeast Asia. They are heading to a lawless place on the border to plan to attack and destroy a place. In the underground drug factory in the area, however, the Brave Group had its own ulterior secrets during the execution of its mission... The decrease in the amount of stolen money confiscated during the operation attracted the attention of the upper reaches of the group. Severe punishments followed, and all members of the group were dismissed and investigated. A senior executive asked them to spontaneously complete an undisclosed task. They were told to rescue a woman Tang Peihan (played by Qi Zimei) and her sister Tang Xiaonuo (played by Jian Siyi) kidnapped by local drug lords in the border area. Completing this task was the exchange for clearing the stain. What's the group's secret? Are the top management hiding something? Why was Tang Peihan kidnapped? The answers to these questions will be revealed to you on iQiyi on December 27th in "Out-of-control Guns and Bullets".
