The ocean contains the history of all humanity. The sea holds the voices of the Earth and those that come from outer space. Water receives impetus from the stars and transmits it to living creatures. Water, the longest border in Chile, also holds the secret of a mysterious button that was discovered in its seabed. Chile, with its 2,670 miles of coastline, the largest archipelago in the world, presents a supernatural landscape. In it are volcanoes, mountains and glaciers. In it are the voices of the Patagonian indigenous people, of the first English sailors and also those of its political prisoners. Like his previous documentary Nostalgia For The Light, Guzman builds up a unique universe of nature, politics, human minds and history by connecting dots from different times from modern Chilean history and constructing visually stunning universe from chain of natural images. The Pearl Button won the Silver Bear for Best Script at the Berlin International Film Festival in 2015.
