Unity Mitford's secret diary comes to an end as war between Britain and Nazi Germany becomes inevitable. She visits the British consul and hands Hitler's adjutant a farewell letter before attempting suicide. Hitler is deeply upset by the news and orders a news blackout on Unity's suicide attempt. She is given the best treatment at a Munich clinic and later transported to Switzerland for further care. Unity's health deteriorates, and she spends her final years under the care of her family and a devoted friend. She dies in 1948 at the age of 33.
