Presented by BAFTA award-winning actress Joanna Scanlan (Slow Horses, Bridget Jones: Mad About the Boy), this powerful series delves into the Herculean challenge facing police forces and prosecutors across the United Kingdom as they strive to secure justice for families—despite lacking the most crucial piece of evidence: the body.

In each episode, Joanna Scanlan investigates an unconventional case, uncovering the extraordinary lengths detectives must go to in order to prove a murder has occurred. The series shines a light on the heart-wrenching stories of families who, even after a killer is brought to justice, have never had the chance to properly mourn their loved ones—still searching for closure after all these years.

Through interviews with the detectives leading the investigations, prosecutors, and experts who helped establish the "no proof of life" principle, the series provides an in-depth look at these complex cases. Viewers will also gain access to key evidence—CCTV footage, cell site analysis, and more—that helps piece together the movements of the suspects.
