Ep 1. Episode 1

In the first episode of Code of a Killer, viewers are introduced to two men whose work will eventually lead to the solving of a high-profile crime that captivated the United Kingdom in the mid-1980s.

The episode begins with the discovery of the body of a young woman in a wooded area near a housing development. The initial investigation offers few clues as to the identity of the killer or the motivation behind the crime, leaving detectives struggling to make headway in the case.

Meanwhile, geneticist Alec Jeffreys (played by John Simm) is working on developing a new DNA profiling technique that he believes could revolutionize criminal investigations. He faces skepticism from some of his colleagues, but remains committed to his research.

At the same time, Detective David Baker (played by David Threlfall) is tasked with heading up the investigation into the murder of the young woman. He brings a no-nonsense approach to the case, but finds himself facing a lack of leads to go on.

As Jeffreys continues to work on his DNA profiling technique, he is approached by a colleague who is hoping to use the new method to clear a man who has been wrongfully convicted of rape. Jeffreys agrees to help, and is eventually able to prove the man's innocence.

Baker, meanwhile, is struggling to make progress in the investigation. He is frustrated by the lack of evidence and suspects that the killer may be someone within the victim's circle. He enlists the help of his daughter, a journalist, to try to gather information about the victim and her acquaintances.

As Jeffreys' DNA profiling technique gains more attention, he is approached by Baker, who hopes to use the technology to help solve the murder case. Initially skeptical, Jeffreys eventually agrees to take on the challenge, and begins analyzing DNA samples from suspects and potential witnesses.

The episode ends with Jeffreys making a significant breakthrough in the case that could lead to the identification of the killer. As he works to confirm his findings, Baker becomes more convinced that the killer is still at large and must be caught before he strikes again.

Overall, the first episode of Code of a Killer sets the stage for a gripping crime drama that blends forensic science with traditional detective work. The acting is strong and the pacing is brisk, keeping viewers engaged as the investigation unfolds. With a rising body count and mounting pressure to find the killer, the stakes are high as Jeffreys and Baker race against the clock to crack the case.
