It all began with an unusual request: "Could you film everything about me until I die?" Masahiro Tanaka was a palliative care doctor and Buddhist priest who was diagnosed with terminal cancer. He was an end-of-life specialist who helped thousands of patients die peacefully. Now he had to face his own impending death. The film crew set out to document an "ideal death", but what they witnessed was quite different. This program offers an unflinchingly honest look at human nature at its most vulnerable.
