A mother-of-pearl button at the bottom of the sea: this is all that remains of the desaparecidos of Villa Grimaldi in Santiago, the torture centre under the dictatorship of Pinochet. The tinkling of the waterfalls: it's the song of water of the Selknams, a native population slaughtered by the colonists. Two slaughters and a liquid memory, these are the narrative tools to convey the story of Chile and its still open wounds.
