It's Halloween, and Huey, Dewey, and Louie are going trick-or-treating. They receive treats from Mickey, Minnie and Goofy (the latter thinking it was Easter and giving them eggs while dressed as a bunny). They visit Donald's house, but Donald disguises himself as a scary man with a hook and a hockey mask and scares the boys away. The boys run away in fear and terror and hide behind a tree. Donald takes the candy that the children left behind as well. Huey, Dewey, and Louie discover Donald's trick and plan to get back at him. They sneak inside the house and put glue on Donald's disguise. When Donald hears someone knocking at the door, he puts his costume back on, hoping to receive more candy. However, Chief O'Hara is there with a wanted poster of a person dressed in Donald's costume asking if he has seen this man since "three young ducks have gone a-missin'". Donald runs away but Mickey, Minnie and Goofy chase after him, believing that he's really the culprit. Eventually, Donald ends up in a graveyard in front of three tombstones with his nephews' names on them. Hewy, Dewy and Louie disguise themselves as zombies, and say that their uncle scared them to death. Donald tearfully promises to get their candy back and the boys dress him up in a costume of their own and make him trick-or-treat with them. All four of them run away, however, when the next person they see in the shadows has a hook for a hand, they get terrified, but it turns out that it was actually Goofy, dressed as Santa Claus, prepared to give the candy canes.
