Synopsis：Lu Yao discovered that his sister had been taken hostage by drug traffickers. The team members suggested exchanging Mile for his sister, but Lu Yao firmly opposed. He even raised his gun and aimed at his own sister. Torn between national justice and personal interest, Lu Yao chose the country. Shocked by Lu Yao's resolve, Mile became afraid and reluctantly ordered his men to release the sister. The team then proceeded with Plan B, heading to a nearby town to reach the border. However, unexpectedly, they walked into a "hell"—a place where Mile held absolute control, fraught with danger at every turn. Not only were drug traffickers hunting them down, but even children playing by the roadside could instantly raise weapons and fire at them. What kind of brutal battle awaits them? What is Mile's real motive for turning himself in? Can Lu Yao and his team escape this "hell" with his sister and Mile, returning to their homeland and successfully completing the mission code-named "Poison Thorn in the Throat"?
