Joong Yeop tells Jae Hwan that his mom’s memories from before the accident are coming back. He has suspicions about the fact that the accident occurred 35 years ago.

Something however, tells Jae Hwan that the case is not over yet. His gut feeling keeps alerting him that the true Chimera might still be at large.

Jae Hwan asks Chief Bae why Hahm Yong Bok got discharged 35 years ago, but Chief Bae becomes defensive and doesn't give him an answer. Meanwhile, Agent Hathaway finds suspicious things about Kang Sang Gu and keeps a close eye on him. However, Kang Sang Gu also has his eyes on her.

After the explosion, Hyo Kyung from UBS Newsroom visits Eugene at her office. She tells her that she believes the Chimera Case from 35 years ago is related to the current incidents. Since they don't have any hard evidence, she asks her to join hands and use the media to find the Chimera Killer.

"It's not over yet," vows Carson. But later, in a post office sorting room, we see Hennessey confiscate copies of an incriminating video that had been mailed to the press.

Peter Carson's subversive investigation uncovers Dr Jenner's dark past, including details of the probably illegal, certainly unethical genetic engineering experiment, he initiated a decade ago.

On his arrival in the sleepy Yorkshire town nearest the Jenner Clinic, the fiendish Government official, Hennessey, orders all police out of the area, and calls up an army of khaki-clad 'specialists' who throw a security web around the site. Highly placed and powerful, Hennessey conducts a cover-up; mutilated victims disappear en route to the mortuary; the press are officially gagged by a 'D' notice; and the regular police's mass-murder inquiry is abruptly cancelled without any explanation to the detective in charge.

While working in a busy NHS hospital, nurse Tracy Pickford gets a better job in a private fertility clinic. The Jenner Clinic is out in the country, very quiet and far away from the bustle of the city. All seems normal, but for the off-limits section where they keep test animals, and the nightshift Tracy is assigned to would be boring except for mysterious activities centring on those out of bounds laboratories.
