Ep 2. Two Below Zero

The episode "Two Below Zero" is the second episode of the fifth season of the long-running British TV show Silent Witness, which is a crime drama series that first aired in 1996. In this episode, the team of forensic scientists and detectives investigate the death of a young woman whose body is found in a frozen river.

The episode begins with the discovery of the woman's body by two fishermen who were out on the river early in the morning. They immediately contact the police, and the team from Silent Witness is called in to investigate. The team is led by Dr. Sam Ryan, the chief forensic pathologist, and comprises of scientist Leo Dalton and detectives DS Nikki Alexander and DI Harry Cunningham.

Upon examination of the body, the team discovers that the woman, whose identity is not immediately known, had not drowned as was initially suspected but had been killed before being thrown into the river. The team then begins the task of piecing together the circumstances surrounding the woman's death, interviewing potential witnesses, and examining the evidence found at the scene.

One of the main challenges the team faces in this episode is the location where the murder occurred. It is a remote area, inaccessible by road, and covered in snow. As a result, the team must use snowmobiles to traverse the area and investigate potential clues. They find an abandoned cabin in the area that they believe could be connected to the case, and they begin to investigate it further.

While investigating the cabin, the team discovers evidence that suggests the woman may have been involved in a love triangle. The victim's mobile phone is found in the cabin, and the messages contained therein suggest that she was involved with two men. One of the men is identified as her ex-boyfriend, while the other is unknown.

As the investigation progresses, DS Nikki Alexander becomes convinced that the victim's ex-boyfriend is responsible for her death. However, Dr. Sam Ryan is not so sure and continues to examine the evidence and explore different possibilities. There are several twists and turns in this episode, and just as it seems that the case is about to be solved, a new piece of evidence comes to light that throws everything into doubt.

Overall, "Two Below Zero" is a gripping episode that showcases the forensic investigation skills of the Silent Witness team. The remote location of the murder and the heavy snowfall add an extra level of complexity to the case and make for an engaging storyline. The episode also explores themes of love, jealousy, and betrayal, making it an emotionally charged episode that keeps you guessing until the very end.
