I'm looking for the literary expression that is used when the themes and plot of a subplot are the real plot of a narrative, which is counterpoised to another, more accessible story plot that is only a vehicle for the main storyline.
It sounds complicated, but I believe that there is a literary term for this.
An example of this would be an athlete trying to win a sporting event against an environment of prejudice, but where political events overshadow the individual's endeavors, and the story is primarily about the politics and the athlete is used as a narrative foil of the political circumstances.
There may not be an actual term for this, but if there is, I'd be happy to know.
