Lim Kyungri is a burglar for the NORA gang. Everyday is a risk for her getting locked up behind bars, but it's the only way to pay her bills after her mom's death and her father leaving her at age 16. Since then, she quitted school and joined a gang that promised to pay her well if she gets her job done right.

Every midnight, she completes her assignment, but after discovering a necklace with a small charm of a glass slipper, Kyungri finds herself in a completely different world where she's dressed in rags, and apparently has two evil step-sisters with a wicked mother.
