Angelina and her ballet class are putting on a special performance of Sleeping Beauty at the Royal Palace. When the production isn't going as planned, and it looks as if the performance will have to be cancelled, Angelina wonders "How will I ever face Miss Lilly?" Will Angelina and the mouselings pull everything together in time for the show? Will Queen Seraphina be pleased?

Angelina can't believe her ears when Miss Lilly announces that she'll be taking her ballet class to headline the Dacovian Festival of Dance! And what's more, they will be sailing to Dacovia on the grandest ship in the whole of Mouseland — The Royal Stilton! On board, Angelina and Alice meet Yuri, the ship's radio operator and nephew of Miss Lilly. When Angelina hears that Yuri wants to marry the captain's daughter, and that the captain is refusing to allow it, Angelina becomes determined to change the captain's mind. When the ship gets stuck on an iceberg, all seems lost — until Angelina has a brilliant idea to rescue the ship and Yuri's plans to marry his true love!

It's Christmas, and Angelina Mouseling (Finty Williams) is auditioning for the lead role in the musical extravaganza, Cinderella Mouse and the Ugly Whiskers. She is devastated when Penelope Pinkpaws (Jonell Elliott) is chosen to play Cinderella and she is cast as the Wicked Stepmouse. Taking Miss Lilly's (Dame Judi Dench's) advice to "think horrid" much too literally, Angelina storms off in a fit of a temper. Then a toboggan race goes wrong and it seems that the production will have to be cancelled. Realizing how selfish she has been, Angelina determines to sort things out, because as every aspiring star knows, "The Show Must Go On".
