Filmed just before the Carnation Revolution of 1974. Dark portrait of a group of friends who used to be colleagues at the University in 1962. Ten years later, they have lost all their ideals. With Lisbon on the background they discuss politics, love, culture; each of them has reached a deadlock. The camera remains still while it registers the dissolution of their dreams.

During an evening, men and women talk about love, life and death. One of them catches a moth and explains to the others the tragic fate of this insect. Everyone recognizes himself in the little animal.
