The leader of the anti-terrorist special combat team, Zhong Yuan, killed the second person of the Mammoth Organization during his mission, which led to revenge. During the operation to rescue his wife Zhao Xin, Zhong Yuan was injected with the virus and was tortured. Jiang Han, chairman of DK Biotechnology, invited Zhao Xin, a first-time lover and a high-achieving student majoring in biochemistry, and his father to participate in the company's "beneficial bacteria" research. The Counter-Terrorism Command Center selects "experts" to infiltrate the company at the request of country T. Zhao Xin, who lost her beloved son, took the initiative to ask Ying to "retire from active service" and go deep into the tiger's den. A series of terrorist incidents have gradually surfaced the "New Era Project." With the cooperation of his beloved wife Zhao Xin and his comrade-in-arms Lu Hao, who "disappeared" five years ago, Zhong Yuan led Qiao Dapeng, Mai Mengmeng and other special combat team members to attack, and successfully smashed the serial conspiracy and biochemical attacks of terrorist organizations, revealing the true face of Jiang Han's use of "beneficial bacteria" as a carrier to create a virus.
