A story with a hole in it is a story told without telling the plot. It is the listeners, or reader in this case, job to try and figure out what the plot is. Or, the reason for the story. You need to figure out what is going on. Why the things happened in the story.
The listener/reader asks questions about the story. Usually just yes or no questions. You will get an answer of "yes", "no", or "irrelevant".
