It's time for Samantha's summer visit again. Both she and Val are anxious to see if they will take another magical journey through the mirror. After learning of a problem with one of the horses, Odette makes her appearance and tells the girls it's up to them to help him.
What Charlie needs is something that can only be found in their magical land. It can't be given to them; they have to solves riddles and discover the answers themselves. A family of elves guides them, but even elf powers are limited when it comes to what stands between the girls and what they seek.
Trolls and unicorns were everything they imagined and more, but rescuing Rapunzel from her tower was an added bonus they never saw coming.
