It's Valentine's Day, and the magical sisters and their favorite babysitter accidentally put a love spell on the kingdom. They must stop the enchantment before it's too late!

In the enchanted land of Harmony, the kingdom and all its magical creatures are abuzz celebrating Valentine's Day. When the King and Queen leave their three daughters -- Angel Scarlet, Princess Daphne, and Fairy Cora -- with Ali the Alligator, so they can spend a romantic dinner together, the sisters are excited for a fun night with their favorite babysitter.

Ali and the girls decide to make a love perfume in the castle's garden. But when Angel Scarlett wants to use her wand to help stir the ingredients, an enchantment of love mistakenly wafts over the kingdom and all its inhabitants. Can the girls stop the enchantment before it's too late? Or maybe it is just what the creatures needed, after all.
