Donald Duck reluctantly takes his nephews Huey, Dewey and Louie to the home of their reclusive great-uncle Scrooge McDuck. Enthralled by their once legendary great-uncle and the wonder of McDuck Manor, the triplets and their newfound fierce friend Webby learn of long-kept family secrets and unleash totems from Scrooge's epic past, sending the family on an adventure of a lifetime to the Lost City of Atlantis.

Louie plans a break-in at a high-class party hosted by Duckburg’s most popular tastemaker, Emma Glamour, so the Three Caballeros can play as Donald tries to get past the party’s no-nonsense planner, Daisy Duck.
