Laure Portier films those she loves. Her second film, Soy libre, takes the form of an informal conversation with her younger brother, Arnaud.

The dialogue is difficult from the outset, as neither Laure nor Arnaud mince their words. They fly out like so many ideas hurled in the face of the world.

Little by little, a fragile and intermittent negotiation takes hold. When it is broken or Arnaud is too far away, Laure entrusts him with a camera and incorporates Arnaud's footage into her film.
