One morning, Jessica Holland, a Scottish orchid farmer visiting her sister in Bogotá, is woken by a loud ‘bang’. This haunting sound dispels her sleep for days, calling into question her identity and guiding her from recording studios to secluded jungle villages in an attempt to find its source.

Sara and Óscar, a couple going through a marital crisis, decide to spend a week in a remote country cabin with their two children, Alicia and Tomás. The family tries to have a quiet time, but something strange happens there. There is a woman who prowls through the forest and cries uncontrollably looking for a baby she has just lost. This deeply affects the family who will have to stay together to survive this nightmare.
