The Wise Little Hen of the title is looking for someone to help her plant her corn. Peter Pig and Donald Duck both feign belly aches to get out of the chore since they would rather play than work. So, with help from her chicks, she plants it herself. Harvest time comes; again, Peter and Donald claim belly aches, but the hen sees through this when boards of their clubhouse fall off showing their little act when they shake hands with each other for evading responsibility. Upon wising up to their ruse, she and her chicks wink at each other upon knowing what to do with Peter and Donald later. She cooks up a tantalizing assortment of corn dishes, and heads over to Peter and Donald to help her eat them, but before she can open her mouth, they already fake their belly aches. Once she asks, they are miraculously "cured" but all she gives them is castor oil, to teach them a lesson. As the hen and her chicks eat the corn themselves, Peter and Donald, with nothing but an appetite, repent with all their might by kicking each other in the rump.
