Over a long weekend, a group of friends gathers together, a diverse representation of the last twenty-five years of the Italian left. Some of them haven't seen each other in a long time; the occasion is the release from prison of a former friend and comrade, accused of killing a judge in the 1980s. Roberto Ferro is on parole and wants to know which of his former comrades reported him. Among the friends, some have achieved privileged positions; others, like Nanni and Malena, have adapted to a more modest life and have retained, at least in part, the ideals of their youth. Malena, an Argentine exile who experienced torture at the hands of the military, had a love affair with Roberto and, before that, a strong bond with a disappeared comrade. Roberto's return reignites personal and political conflicts within the group.
