PREMISE

Just when it looks like Storybrooke can enjoy some peace, once more it is threatened by dark forces. The malevolent Mr. Hyde, now separated from Dr. Jekyll, has arrived and brought his fellow inhabitants from the Land of Untold Stories. To make matters worse, Regina's dark half - the Evil Queen - continues to exist despite her heart being crushed; unburdened by a conscience, the Evil Queen has declared war on the heroes. Meanwhile, Aladdin's past as the previous Savior becomes a new factor in Emma's role as the current Savior, and is about to be pushed to the limits, which could lead her to a future that has no happy ending for her, while Gold must deal with trying to win Belle's heart again so they can be a family for their future child.
