英国著名作家Terry Pratchett患上了阿兹海默症，逐渐丧失写作能力的人生对他来说毫无生存价值，于是他开始思考自愿选择结束生命的可能性，走访了曾经选择过或正在决定安乐死的几个对象并拍下了这部纪录片。片中你将亲眼目睹死亡。

In 2008, celebrated author Sir Terry Pratchett was diagnosed with Alzheimer's disease. Nearly three years on, Pratchett considers ways to end his life before the disease consumes him. His search takes him to Switzerland, where he meets some of the staff and clients of a non-profit organisation that provides assisted suicide to people suffering from severe ailments and terminal illnesses. In a quiet cottage outside Zurich, we—along with Sir Terry—witness a man's final moments with his wife.
