This drama tells the story of the four men killed by Stephen Port: Anthony Walgate, Gabriel Kovari, Daniel Whitworth and Jack Taylor, and their families and friends who worked tirelessly to find out what happened to them.

Stephen Port received a life sentence with a whole-life order in November 2016. An inquest into the four murders concluded last week, with the jury ruling that failings by the Met Police contributed to the deaths of Port's final three victims.

Four Lives was initially announced with the working title of The Barking Murders.

Jeff Pope and Neil McKay previously worked together on The Moorside, which told the story of the community impacted by the disappearance of Shannon Matthews; and Appropriate Adult, which looked at the story of serial killer Fred West from the point of view of trainee social worker Janet Leach.
