On the roof of the Benedictine convent of Lazkao, an ikurrina with black ribbons appeared during the Mass by Txabi Etxebarrieta. Ikurrina was illegalized and confessing to an ETA member was challenging the regime.

In the church appeared a series of the extreme right group "Guerilleros de Cristo Rey", displaced by Irún. “Cabrons!” and “Maricones! "started screaming at those who had the courage to show up like this.

Meanwhile, little Eustachian Mendizabal descended with ikurrina in the tower. When ETA lost its first militant, Txabi Etxebarrieta, an unexpected movement emerged from villages: Mass by Etxebarrieta.
