The documentary tells the story of a group of students from the National High School of Buenos Aires, who in the early 1970s led and formed the Union of Secondary Students. They were between the ages of 15 and 19. They lived through days marked by love, activism, clandestinity, and danger, until state terrorism violently interrupted their adolescence. Today, many of them are missing. Others have returned from exile. The previously unseen images of those days are fragments of memories, woven together by the survivors' accounts as a testimony for new generations.
