Veintitrés fotografías

Sol is a thirty-eight-year-old publicist in the middle of a labor and sentimental crisis. One day she, on impulse, buys an analog camera in the Madrid flea market. When she develops the reel, she discovers twenty-three photographs showing a couple's wedding. Sensing a call from the past, she becomes obsessed with the newlyweds and a mysterious man who stands out among the guests. When she decides to investigate them, the questions arise: who are the protagonists of those photos? Where are they? Are they still alive? Sol still doesn't know that the story contained in those snapshots will blow up her life completely.
