Today's guess of the plot will be very poor of comments on my side, for reasons I will disclose in due time. Also, it is unfortunately a rather expert-only one, since it represents something that experts will surely recognize for its generalities, while only the details will probably remain mysterious to them.
I will be glad to read your guesses in the comments thread, which I hope will be plenty and insightful. Hopefully in a few days I will disclose what the plot represents.
UPDATE: In place of the plot, events force me to put in its place something else, for just a few hours. See below - the change is not dramatic, but what is added is probably giving a stronger hint than what is taken off.
