After the doomsday comes, the word regret is engraved into human genes like a virus. Qin Jin, a former special soldier, bears the sin of the death of all his members and wanders the wasteland, using a precognition chip to avoid death, but refuses to escape. Doctor Shen Tang tried to save him, but he didn't know that he was the source of his regret. The old cripple spreads the faith of regret, Tie Ya feeds on pain, Egret struggles with betrayal, and Zhou Ya waits for the collapse of the truth with a silent broadcast. When 'regret' becomes the price of survival, which of them is the real seed of doom?
