Those Who Kill, A&E's thrilling new drama based on the Danish crime series format inspired by the bestselling work of author Elsebeth Egholm, follows Catherine Jensen (Academy Award-nominated and Golden Globe-winning actress Chloë Sevigny) a recently promoted homicide detective who tracks down serial killers and relentlessly seeks the truth behind the disappearance of her brother.
As a freshly minted homicide detective, Jensen has garnered a reputation for overstepping her boundaries in her unrelenting pursuit to solve Pittsburgh’s most gruesome murders. Motivated by her past, including the disappearance of her brother and the suspicion that her stepfather is a serial killer, she often finds herself emotionally connected to the victims she’s investigating. Jensen enlists the help of Thomas Schaeffer, (James D'Arcy), a forensic psychologist who has a tumultuous relationship with the police department, to provide insight into her cases and her personal investigation into her stepfather. He too finds himself deeply connected to each case, but often through the killer, which proves to be a hazardous undertaking. The pair shares a skewed sense of judgment that often puts them, and sometimes even their families, at risk. As these two captivating yet flawed characters come together, their bond often rescues them from their individual demons but may be the source of more harmful tribulations.
