Lara Winslet is an expert geologist in volcanology. She is together with her team of work on a volcano to conduct surveys. At the end of a working day, Lara decides to stay a little longer to finish an exam and she remains so alone. Returning, she has an accident, falling inside a hole in the ground and remains blocked inside there, where no one can neither see nor hear her. This experience will lead her to take an examination of her whole life and to think of her daughter.—A. Smith Luise
