Michelle (Mary Elizabeth Winstead), a young woman, wakes up after a car accident with her leg chained to a wall and locked up in an underground bunker.
A bulky old captor Howard (John Goodman) turns up, narrates how he saved her from a large-scale attack by either Martians, Russians or North Korea. That the air outside is not breathable and they will have to live underground for one or two years at least. He assures her that nobody is alive out there. Michelle suspects otherwise.
Building up consistent nerve-wracking suspense, 10 Cloverfield Lane is a high-quality sci-fi thriller. The final act holds up, despite a much-visited premise, for the dark execution and grit. Highly recommended.
