A crossword is a puzzle that usually takes the form of a square or a rectangular grid of white and black squares. The game’s goal is to fill the white squares with letters, forming words or phrases, by solving clues leading to the answers. An old man is solving a crossword containing various clues. Some of them are easier, some tougher, but they are all related to events in his life. Is it just a way to kill the time or maybe it’s going to be something more important for him?
