Vivaldi, barely into her teens, is already a “former” promising fencer. Suddenly incapable of winning, her mother forces her to watch video footage of herself: her fencing competitions are taped over home movies of the last family holiday before her parents split up, when she was still a little girl. A technical glitch with the tape means that the past resurfaces in the form of enigmatic fragments. One of them, a video she shot herself when she was a child, will reveal something that had always been kept secret from her until now, forcing her to confront her passage to adulthood head on.
