Qin Chuan, an ordinary military academy student with poor performance in all aspects, and his comrades Ning Zhi and Zheng Yong were selected into the mysterious "Special Case Team". They conducted brutal training together and established an extraordinary friendship and tacit understanding. When they carried out their first mission with passion, they suffered a disastrous defeat. Zheng Yong died, Ning Zhi was seriously injured, and Qin Chuan was "returned". At this moment, Qin Chuan received an order from his superiors to go to the "Golden Triangle" and cooperate with Cheng Jianbang, who was ambushing there, to approach the drug lord Zhou Yadi, and began a cruel special mission.
Zhou Yadi was in prison at the time. Cheng Jianbang originally planned to rob and imprison him to get close to him. Unexpectedly, when he was implementing the plan, he was intercepted and was only sentenced to "attempted robbery" and was sent to another prison. The task of getting close to Zhou Yadi fell on Qin Chuan, who had just arrived, but he struck too hard and was sentenced to death. Fortunately, before the execution, things took a turn for the better, and the sentence was changed from death to 20 years in prison. It was also a blessing in disguise, and he entered the same prison as Zhou Yadi. But it was not so easy for him to find Zhou Yadi. After going through a series of stories, he found the target, but the target was killed. When he was desperate, the real Zhou Yadi appeared, and there were twists and turns...
