Cinto turns 100 on Sunday and his whole family is staying with him for the weekend. Over the years, he has taught them all the stars and constellations, the names of which he first learnt during the Civil War. During his time with the "Quinta del Biberón" youth troops, there was one star in particular that held a very special place. Of course, both his son, Quim, and his grandchildren, Paula and Ramón, have also had their own wars. Like everyone else, yes, but theirs may have been even riskier. After all, they lived for a time in the Basque Country. And their love stories are dangerous and have consequences. However, whatever happens, every night they will gaze up at the stars that will forever unite the four generations.
