David Sieveking left home years ago to make films. Now he has returned – and for a reason: To help his mother, Gretel, who has Alzheimer’s, and relieve her long-time carer and his father Malte for a few weeks. The filmmaker takes on the role of carer and documents this encounter with his camera. Gretel no longer knows the people around her, but her puns and charm have not faded. The time spent with his mother becomes a journey into David’s unexpected family history. Once active in Zurich’s left-wing scene, David’s parents enjoyed a lifelong “open relationship”, characterised by a loving distance and mutual respect. VERGISS MEIN NICHT is a film about dementia, but it’s first and foremost a declaration of a love of life and family.

Joel Barish, heartbroken that his girlfriend underwent a procedure to erase him from her memory, decides to do the same. However, as he watches his memories of her fade away, he realises that he still loves her, and may be too late to correct his mistake.
