When the mystery of toxicology collides with a transnational conspiracy, when the game of life and death becomes entangled with fateful love, the mutation of the "miracle" toxin causes trouble again, and the death of Peng Changsheng, an old case, reveals a shocking secret.
Luo Jiaxi: "Sheng Xiyu, I bet the truth will come out, and I bet you will be safe in this life."
Sheng Xiyu: "My battlefield is half of my country and half of it is you."
Concept: There are no industrial saccharine and bloody misunderstandings. Life and death on the border in troubled times are the background. Love is hidden in fighting side by side and guarding in desperate situations. The righteousness of family and country blends with personal love, and the pattern is elevated.
