It centers around a magical doll named Sindy, Despite appearing as a normal toy in our world (being a Christmas present for Molly) finds herself waking up in a mysterious land someplace else.
A stranger to this world, Sindy is assisted by three fairies, who, after mistaking her for the evil wizard Azbar, explain the circumstance - grumpy Prince Hugo is looking for a potential suitor so he can inherit the Kingdom. Problem is that he's rejected every woman he's met so far - and if he doesn't find a wife soon, he won't inherit his parents' power, leaving the Kingdom vulnerable to Azbar himself.
Coincidentally, Sindy meets Hugo and he finds himself falling for her, while Azbar plots to set them apart. Entangled in a royal romance and a Race Against Time against the mage, Sindy works to earn her happy ending.
The film has come under scrutiny for its similarities to Mattel's line of Barbie dolls.
