Angelina is brimming with excitement for the most important event in all of Mouseland. She and her friend Princess Sophie have been chosen to be bridesmaids at the magnificent Royal Wedding. Dressed in fluffy dresses, they arrive at the beautiful summer palace ready for a perfect day of celebration. But when the big day arrives, the two young bridesmaids get completely swept up in the magic of the palace gardens. They are so busy dancing and exploring the grounds that they accidentally lock themselves inside a dusty old tower. Trapped high above the gardens with the wedding processional about to begin, Angelina and Sophie must figure out a way to signal for help. They hope someone will hear their calls and come to their rescue before they miss the royal celebration entirely.
