Stephen Hilder, a 20 year old army cadet and sky diving enthusiast fell to his death on a formation display jump on July 4th 2003. His main and reserve parachutes had been deliberately sabotaged. The police immediately launched a murder inquiry. Nine months on, and with no credible suspects, a forensic breakthrough led the police to the conclusion it was suicide. But the inquest returned an open verdict. There was massive media interest and misinformation about the sequence of events leading up to the jump. So what do those closest to Stephen and to the investigation believe really happened? This film re-examines the evidence available at the time and subsequently.
