Lynn Gilderdale spent seventeen years bedridden with severe ME before she died in 2008, and her mother Kay was charged with attempted murder over helping her do it. Panorama cameras follow Kay Gilderdale for close to a year, through the run-up to her Old Bailey trial and the verdict that followed: acquitted of attempted murder, but sentenced to a conditional discharge after admitting to aiding and abetting suicide. The film sits with Kay at home and in the courtroom corridors, tracking a woman facing a possible life sentence for what she describes as ending her daughter's suffering rather than her life. Interviews and access built up over the ten months of filming let the case unfold in something close to real time rather than as a summary after the fact. The broadcast lands in the middle of Britain's live argument over assisted dying, using one specific family's ordeal, and one specific legal outcome, to show what that debate actually costs the people living inside it.
