Ep 1. Pilot

Those Who Kill is an American crime drama television series based on a Danish television series bearing the same name. The series revolves around the central character, homicide detective Catherine Jensen, as she investigates serial killers while struggling with her own troubled past. The first episode of the series is titled "Pilot" and appeared first on March 3, 2014, on A&E Network.

The episode begins with Catherine Jensen, played by Chloe Sevigny, inspecting a crime scene in Pittsburgh, Pennsylvania. It is a dark rainy night, and a woman's body has been discovered in an alleyway with her throat cut. The victim is identified as Sarah Brine, and Catherine notes the similarity of the killing with two other murders that had taken place in the previous weeks. Catherine seems quite obsessed with the case, and her supervisors are worried about her mental state.

Meanwhile, the viewers are introduced to another primary character of the series, Thomas Schaeffer (James D'Arcy), a forensic psychologist who is working with the FBI and the local police department to track down the serial killer. Thomas has a somewhat mysterious personality, and Catherine seeks his help regarding the case. Thomas is initially reluctant to work with her, but Catherine's persistence persuades him to join her.

As the episode progresses, we learn that Catherine has a dark personal history. She was kidnapped and abused as a teenager and believes that the same killer who is responsible for Sarah Brine's murder is also the one who took her captive years ago. This revelation explains her obsession with the case and her troubled mental state.

Catherine's colleagues are skeptical of her theory, and she is criticized for her methods. However, Catherine's insistent efforts lead her to a suspect, a local store owner, who's inquisitive personal behavior is considered peculiar. Catherine, accompanied by Thomas, pays him a visit, but they leave with no conclusive evidence. The plot becomes more intriguing, as we see the killer's perspectives in the episode.

The episode ends with a cliffhanger as a mysterious stranger contacts Catherine, informing her that she's onto the right track. Thomas also discovers that the suspect leaving their premises had a suspicious-looking object in his bag. The viewers are now left curious as to what lies ahead and whether Catherine's suspicions are correct.

Overall, the pilot episode of Those Who Kill lays the foundation for the series's premise by presenting a combination of the aspects that define the show. The episode is well-crafted in its cinematography, music choices, and visual representation of violence. The acting of the cast is praiseworthy and keeps the viewers engaged throughout the show. Furthermore, the establishment of Catherine's backstory adds depth to her character and translates a personal touch to the audience. With an engaging plot, strong performances, and a dark theme, the viewers are in for a thrilling ride in Those Who Kill's subsequent episodes.
