Donald receives a postcard from his sister, Dumbella, which says that her three "angelic" boys, Huey, Dewey, and Louie, are coming for a visit. At first Donald is excited to see his nephews, but once the trio arrives all hell breaks loose. Instead of angels, the boys turn out to be little demons as they constantly annoy their uncle. Donald consults a book titled Modern Child Training and tries to have control over his nephews, but it only ends in disaster. In the end, after the boys leave and his house almost destroyed, Donald spots a page which read "After all, little children are only angels without wings" This so angers Donald that he rips the book to shreds and goes into an explosive rage.
