Elisa and Alexandre meet during a weekend at Caramulo. They are both young, belong to different circles and generally see the world from opposite perspectives – and yet they seem incapable of avoiding the attraction that slowly engulfs them. Willing and hesitant, they begin a relationship they do not entirely understand and often question. But that will mark them forever.
Elisa is afraid of the moon and of windows without curtains, thinks too much and wants to understand the world in its multiple aspects. Alexandre, on the other hand, goes through life without much thought, mainly worried about enjoying the present before responsibilities seize him.

A Bildungsroman, The past we shall become gives us the portrait(s) of a generation and the paths where it searches for “its” truth.

There is in the voice of each individual the plenitudes of a thousand stories.
This is Elisa’s and Alexandre’s narration, the tale of their cities, of the places where they lived, the people they met, the cheerful conversations, the joys, confusions, discouragements, of the certainties they gathered and the ones they lost, of the consequences arising from what they decided and chose. But it is likewise the story of two idiosyncrasies and memories, of the imagery that informs them.
Elisa cannot forget her childhood or the wondrous, living captive of what happened and haunted by old fears, enthralled by both dream and nightmare. Alexandre cares little for either, but knows the present in a way Elisa can hardly understand or mimic. Influenced by one another they keep moving forward, all the while trying to comprehend what surrounds them and escape the flow. Sooner or later they will have to choose, and that shall define them.
