Imagination is sometimes more powerful than any image. Calls traces several sound recordings found after tragic events, all connected in one way or another to an impending Apocalypse. From the black box of an airplane to the cassettes of a tape recorder, we discover several stories mixing the strange, the anguish, the love and sometimes even the inexplicable. Without images, everything becomes bigger, everything becomes personal, everything becomes part of your mind and your creativity. You participate in the story. You are the director.
