Jeanne, 34, lives in Paris with her husband Nathan and their two children, Jérémie and Léa, 8 and 6. One day, her husband buys a small video camera and starts to film the family's daily life. In the video footage, Jeanne discovers that many details of her surroundings appear differently from how she sees them: the place and shape of objects isn't exactly the same. The behaviour and appearance of her family are also modified... Jeanne remarks on this in surprise but she is the only one to see these details as changes. For her husband and children, these changes seem to have always been part of their surroundings - as if Jeanne's memories had never existed!
