The episode centers around the legendary figure known as the Iron Mask, a mysterious prisoner whose identity has long been concealed behind a mask made of iron.

As the family arrives at the Iron Fortress, they are immediately caught in a web of intrigue and danger. They quickly realize that the Iron Mask is not just a prisoner, but rather the key to a bigger mystery—he holds the secret to an ancient treasure that could change the course of Duckburg’s history. But the fortress is filled with obstacles, traps, and secrets, and they must navigate them all to uncover the truth.
The twist comes when they learn that the Iron Mask isn't simply a prisoner, but a powerful and strategic individual whose true identity will change everything. In a stunning reveal, it turns out that the Iron Mask is actually a member of the McDuck family—Scrooge’s long-lost relative, who was hidden away to protect the family from a great danger. The episode explores this family history and the reasons behind the secretive actions taken by previous generations of McDucks.
The McDuck family must work together to uncover the truth behind the mask, all while facing off against rivals and dangerous adversaries who also seek the treasure. Magica De Spell and Flintheart Glomgold are once again involved, eager to claim the treasure for themselves and defeat Scrooge once and for all. Along the way, Scrooge and the kids must rely on their wit, teamwork, and courage to navigate through the twists and turns of this mysterious adventure.
In the end, Scrooge McDuck is able to save his long-lost relative and reveal the truth about the Iron Mask. The McDuck family learns valuable lessons about their heritage, the importance of family bonds, and the lengths to which Scrooge has gone to protect those he loves.
