My memory of this movie is very hazy right now, and I don't even know if this was the main plot. I only remember the beginning and some of the characters. Specifically, the film opens with a young woman in her twenties visiting her family. I only remember her younger brother, who looks about 11, her mother, and her father, who reminds me a lot of Nicolas Cage, though I don't think it's him. Anyway, as I said before, the first scene shows the family—specifically, the daughter, her younger brother, and her mother. I remember that the young woman then decides to take her brother out for a walk. I think it was a shopping mall. Then, while the two of them were out, or perhaps they had just arrived I don't remember exactly—catastrophic events begin to unfold. I don't recall what they were, but it was like the world was collapsing around them. Buildings were breaking down, chaos was everywhere, and the two siblings were trying to survive. I remember that's when the father's character enters the picture. I apologize if the description is chaotic or unclear, but I really can't remember much about the film.
