When a heat wave envelops West Monroe, the air conditioning unit at the Duck Commander warehouse goes down, turning the duck call assembly room into a boiling sweatshop.

Meanwhile, Willie hires the local Mr. Fix It, Mountain Man, to get the AC unit up and running once again, which proves to be a painstakingly slow process.
