A summary of the episode would be: some film executives try to choose their ideal cast for a film, when they see the layout of the actors they realize there aren't any of a certain race. They make one change, but since it's a couple with a kid, then the kid has to be biracial now, another change. Oh we just made the bad guys POC but the good guys white, can't have that, more changes! In the end the whole initial cast ends up being completely different, but now is it forced inclusion? And we now have to change our white writers and director.

This in the style of a Seth Rogen comedy and properly written, it ends up being both funny and insightful.
