The alarm tells the strange experiences faced by a group of characters in a near and dystopian future. No one knows exactly why, but it is impossible to go outside. A couple is forced to live with an unknown family while the world beyond the windows of their house seems to disintegrate forever. But the biggest threat of all might be inside, in the exact center of the dining room table. Or at the bottom of the nightstand drawer. Or in the past.

When a former neighbor from their hometown reports that she has seen the ghost of Irene, the daughters do not believe her. After a murder and a family tragedy, however, Irene's spirit materializes around her daughters to comfort them.
