Having recently witnessed the death of her husband from a neurological disease, Dr Anne Turner is diagnosed with a near-identical illness and determines to end her life once her condition has reached a critical point. As her health deteriorates, Anne's son, Edward, and two daughters, Sophie and Jessica, struggle to reach a consensus over their mother's intentions to end her life in an assisted dying facility (Dignitas) in Switzerland (where this is legal) and while they search for alternative options, silent recriminations and stubborn practicality threaten to tear the family apart. With her family at loggerheads, Anne must also face the fury of her best friend, whose opposing views bring them into direct conflict.[6]
The film was inspired by the true story of Dr Anne Turner (25 January 1939 - 24 January 2006), who took her own life in a Zurich clinic, having developed the incurable neurodegenerative disease progressive supranuclear palsy (PSP). Before being diagnosed with PSP, Dr Turner had nursed her husband until he died from a similar disease, multiple system atrophy (MSA).[8] Her brother also was victim of a progressive condition, motor neurone disease.[9]
