"Tears are the only way I can miss you"
Four kids whose family was ruined by drugs
Forensic doctor Xu Shanhe, undercover agent Li Biegui, undercover agent Jiang Juehuan, and trace master Chang Heqing are the strongest F4 on the anti-drug line, and they are each other's only escape route.
They use their faith as a torch and life as a shield. They trade their youth for safety in drug dens, autopsy tables, and border mountains and forests.
But the anti-drug battlefield is never perfect. Some people stay before dawn forever, and some carry their will to keep the promise they can never wait for.
Purpose: To pay tribute to the border anti-drug heroes, protect the mountains and rivers with youthful blood, and remember every unknown person who sacrificed for the anti-drug cause.
