Plot Synopsis

YORKSHIRE RIPPER: THE SECRET MURDERS is a two-part documentary that chronicles the story of a seemingly unstoppable murderer the press named the Yorkshire Ripper, who terrorized England in the 1970s. Ultimately convicted of 13 murders and 7 attempted murders, Peter Sutcliffe may have been responsible for dozens more. Through interviews with the victims' loved ones, investigators, and eyewitnesses, these unsolved killings are explored by methodically piecing together evidence pointing to Sutcliffe -- and showing that several men convicted of the crimes were actually innocent. Both installments made their U.S. debut on Tuesday, April 19, 2022 on SundanceNow:

Part 1: The investigation reveals evidence showing that the Ripper's campaign of murder and mutilation started years before his first confirmed victim.

Part 2: As the murders continue, pressure builds on the police to catch the Ripper, while also disregarding similar cases in West Yorkshire and across the country.
