Maybe it was a hiking trip gone wrong and the survivor got lost while the rest of the group perished in an unexpected blizzard or a landslide. Another key event is the struggle for survival alone. This includes finding shelter, food, and water in a harsh environment. And finally, the discovery and rescue, which is a crucial turning point where the survivor's ordeal starts to come to an end.
