Underworld tycoon Lin Shuo received a call from the "god of death" at his peak moment and was told that he only had 72 hours left to live. The only chance of survival is to travel back in time to save strangers - with each person saved, the death countdown increases. When he completed his 99th mission, he discovered that the person he rescued was the enemy who destroyed his family. At this time, the ultimate order came: kill the first girl he saved. The moment he raised the gun, he saw the birthmark on the back of the girl's neck that was exactly the same as the enemy's...
A fatal game about redemption and revenge, time and cause and effect, suddenly reversed before the countdown reached zero.
