The MST recruits most of its members in shanty towns. After weeks of preparation, they are driven in secret to the targeted plots.
In the dead of night, in what has become a symbolic act, the poor "cut the wire" around the land. At dawn the families are divided into "nucleos", to begin building the camp.
