Tijdens een rechtszaak ziet een foute advocaat Ernest P. Worrel in de jury zitten. Ernest lijkt echter sprekend op zijn cliënt, de crimineel Mr. Nash en hij regelt een wisseling. De ruige Nash neemt Ernest's baantje bij de bank over, terwijl Ernest de doodstraf van Nash krijgt.
Nee, helaas is Ernest Goes to Jail nog niet beschikbaar op Netflix in Nederland.
