In the center of the plot is the billionaire Scrooge McDuck and his three grand-nephews - Billy, Willy and Dilly. Previously, they were cared for by their uncle Donald Duck, Scrooge's nephew, but he goes to the navy and temporarily transfers custody of Scrooge's boys. Although Scrooge is the richest drake in the world, he never stops looking for ways to increase his capital. The main event of many episodes is an attempt by Scrooge to protect wealth from the villains who wanted McDuck's bankruptcy.
The main negative characters are a family gang of swindlers named Gavs brothers, headed by Mommy Gavs, as well as a sorceress Magika De Hypnosis, who dreams to get McDuck's first dime, confident that it is in him the source of his luck and wealth. However, Scrooge's most arch-enemy is billionaire Flinthart Glomgold, who dreams of winning the title of the richest drake in the world. Also in the center of some episodes is the First Dime, earned by Scrooge, and which he keeps under the strictest guard in the money vault, periodically protecting him from being stolen by various villains.
