Terry Pratchett, the fantasy novelist diagnosed with early-onset Alzheimer's in 2007, sets out to find whether he could ever choose the manner of his own death. Director Charlie Russell follows him to Switzerland, where the clinic Dignitas legally assists suicide, and into the homes and hospital rooms of people weighing the same decision in Britain, where it remains a crime. The film's most disputed scene is unflinching: Peter Smedley, a hotelier with motor neurone disease, drinks the lethal dose at Dignitas and dies on camera while his wife holds his hand, becoming the first such death shown on British television. Pratchett interviews doctors, campaigners, and families on both sides, including people who changed their minds partway through the process, and lets his own uncertainty about his future stand alongside theirs. The tone stays plain rather than persuasive, following the paperwork, the waiting, and the ordinary rooms where these decisions actually happen instead of arguing a single verdict on assisted dying.
