Premise: Twins Shimmer and Shine are genies-in-training who grant wishes for their best friend, Leah. The wishes don't always go as smoothly as they plan, though -- after all, they're still in training -- and the girls must clean up the magical mess that results from the issues. When Shimmer, Shine and Leah work together they are able to solve the problems that arise and make things right. Trying to correct their mistakes helps to teach young viewers about learning from mistakes and doing better next time.
As the girls search for Leah's lost necklace, an underground creature finds it and begins making wishes with it; after Zac wishes to stay in Zahramay Falls forever, the children search for a powerful genie to reverse the wish.
