In a not-so-distant nightmare future, the hot new reality show on TV is Old Actor Fights which pits two aging actors (ie. anyone over 35) in a ring with a set of sides to wrestle for. The victor doesn't get the role; he (or she) merely wins the chance to engage in an endless obstacle course of auditions and call backs in which demented "judges" make arbitrary casting choices to fill the roles in yet one more episode of (fill in blank with favorite 14th-season TV show).
When the loser of this game show decides to avenge himself upon Hollywood's power elite, he and his "senior" colleagues learn that knocking off the competition is often the shortest path to a successful career in show business..
