If the character starts and ends in the same place, the plot has gone in a circle.  For example, if Charlie was having problems with his teacher at the beginning of the story, and the story talks about the many weeks he has tried to fix these problems, yet the story ends with him still not resolving these problems, the plot had gone in a circle.  There is not resolution, no ending, no fix.
