I'm not sure specifically which 'Saving Nora' story you're referring to. It could be a very specific tale from a book, movie, or someone's personal creation. Without more context, it's hard to tell the full story.
Since I don't have the details of 'Saving Nora' novel, it could be that Nora is in a place where she needs to be rescued. It could be in a physical sense, like being trapped in a place. Or it could be in a more metaphorical sense, such as being trapped in a cycle of bad habits or false beliefs, and the novel is about the journey to free her from that.
Another possibility is that in a modern - day setting, Nora is a victim of a natural disaster. Maybe she's stranded on an island after a tsunami or a hurricane. A group of rescue workers or volunteers then try to save her. They have to deal with things like limited supplies, bad weather conditions, and the search for a safe way to get her off the island. This kind of story could show the heroism of ordinary people in extraordinary situations.
The ending of 'The Birds' is both mysterious and thought - provoking. After the intense and harrowing experiences of being attacked by the birds, Melanie, Mitch, and the others are able to get into a car and start to drive away. The birds that were once so aggressive have become quiet. Hitchcock deliberately left this ending open - ended. It could be that the birds' aggression was a short - lived phenomenon, or it could be that they were simply following some instinctual pattern that had run its course. This ending also serves to heighten the sense of dread and the unknown. We are left with the characters, and by extension, the audience, still in a state of fear and uncertainty as they leave the scene of the attacks, not knowing if the birds could resume their attacks at any time in the future.
