El Eco del Caracol.

Enoc, a boy from an indigenous community fighting against the dispossession of his lands, is afraid to return home to explain everything to his mother without Nathil, his little sister. He suspects that the army killed her when they fired on the protest that the people of his town were holding. Frightened by the bells that call people to mass for the dead, he desperately searches for her among the rocks and waves of the sea.
