Season 1

This gripping true-crime series explores cases of innocent people murdered in their own homes by someone they thought they could trust and, in some cases, had known for many years. The series brilliantly delves into the stories of those that unknowingly opened their door to evil with tragic consequences, as told through the eyes of those they left behind. Each story is supported by testimony from friends and family of the victims as well as a number of the detectives, police officers and forensic experts who worked on the case. With crime scene photographs and specially-shot filming at each location, helping to retrace the steps of the murders, each episode will provide a full 360-degree perspective of the intricate investigations in each case and, ultimately, aim to reveal the motives for the murders.
