After a decade of cold war, Scrooge McDuck reunites with his estranged nephew Donald Duck when he is asked to take care of his three nephews Huey, Dewey and Louie. The new arrivals rekindle Scrooge's sense of adventure, and he invites the four to live at McDuck Manor with him, his housekeeper Mrs. Beakley and her granddaughter Webby Vanderquack. Together, they embark on many new treasure hunting expeditions and globetrotting adventures while contending with villains such as Flintheart Glomgold, the Beagle Boys and Mark Beaks. In Season 1, Dewey and Webby seek the truth behind the strained relationship between Scrooge and Donald and the disappearance of Della Duck, the mother of the three ducklings, while the witch Magica De Spell manipulates events to facilitate her return and revenge on Scrooge. In Season 2, Scrooge and Glomgold compete to become the highest earner in a year, the ownership of both companies is threatened, and Louie tries to start up his own multi-million dollar business in hopes of following in Scrooge's footsteps. After escaping from the moon, Della is reunited with her family and adjusts to being a new mother, unaware that the "friends" she made on the moon are planning an alien invasion.
