A great promise of love. Fate strikes Nina Zacher out of the blue. In her early 40s, the mother of four is diagnosed with ALS, a disease that slowly deteriorates the body while the mind remains fully alert. Instead of retreating and waiting for death, Nina Zacher goes public. Tens of thousands follow the young woman and mother of four small children on Facebook. She writes honestly and directly about her life, her suffering, and her dying, demonstrating immense strength and courage. Until shortly before her death, she shares her thoughts, and when she can barely move, she writes her texts using a special eye-tracking computer. She can no longer fulfill her greatest dream of writing a book. However, her husband grants her this final wish, fulfilling his promise to continue the determined fight.
