Scrooge owns a giant skyscraper which he operates as a first-class hotel for millionaires. Unfortunately, also the Beagle Boys have settled down in it. They steal from the guests and enrich themselves at the cashpoints. Scrooge is powerless, since the police is not responsible for buildings of this size. But with the help of Launchpad, Huey, Dewey and Louie Scrooge manages to flush the impudent crooks to the way out in a bubble bath avalanche. Outside the building, the police is allowed to arrest the lathered thieves.
