Memoria

In Bogota, Jessica, a botanist of Scottish origin, is suddenly awakened in the middle of the night by a loud, metallic sound that only she seems to hear. As this mysterious "bang" torments her at all hours of the day and night, she decides to find out why this strange noise is haunting her. While visiting her hospitalized sister, she befriends an archaeologist in charge of an excavation project, and a musician, who helps her recreate the famous "bang" using a sophisticated sound system. But it is elsewhere, outside the Colombian capital, that Jessica will find answers to her questions.
