Ever since being startled by a loud ‘bang’ at daybreak, Jessica is unable to sleep. In Bogotá to visit her sister, she befriends Agnès, an archaeologist studying human remains discovered within a tunnel under construction.
Jessica travels to see Agnès at the excavation site. In a small town nearby, she encounters a fish scaler, Hernán. They share memories by the river. As the day comes to a close, Jessica is awakened to a sense of clarity.
