Screening as part of Channel 4’s Generation Next season, documentary strand First Cut continues. In 1997, 13-year-old Sussex schoolgirl Billie-Jo Jenkins was found brutally murdered in her back garden. Her foster father, Sion Jenkins, was convicted of the killing, only to be freed in 2006 after a second retrial failed to produce a verdict.

But rather than settle for a quiet life, Jenkins is publishing a book that sensationally claims to have identified a possible ‘new suspect’, in the hope that this will re-open the case. This film follows Sion over four months as he prepares to tell his side of the story for the first time.
