On the day Elena officially becomes Crown Princess, she must rescue her sister Isabel from aboard a missing ship.

Elena is torn between a promise she made to help Isabel and fulfilling her royal duties as crown princess.

Elena laments how she was trapped in the magical Amulet of Avalor for forty-one years, until she was set free by a brave young Princess: Sofia The First.

Elena brings all the communities of Avalor together to share each other's holiday traditions. But when a Doña Paloma scheme causes an overly competitive atmosphere, Elena sets off on a traditional "parranda" and carols through the city to remind everyone of the true spirit of Navidad.

Elena travels to the realm of the jaquins, but unknowingly puts Avalor in danger.
