Synopsis
Master storytellers Edward Kitsis and Adam Horowitz (“Lost,” “Tron: Legacy”) invite everyone to join Emma Swan, Snow White, Prince Charming, the Evil Queen, Hook, Rumplestiltskin and all the other resident fairy tale characters as they cope with Emma’s new role as as The Dark One and begin the search for Merlin. This is a journey that will take our heroes from the Enchanted Forest to Camelot and along the way bring many surprises, including encounters with a brave and headstrong Scottish princess named Merida.

As the season continues, new fairy tale characters will be revealed and old acquaintances will be revisited. Not everyone can be trusted but one thing remains true — you never give up on the people you love...

Story
An infant known as Emma is sent away to a distant land when the Evil Queen's Dark Curse hits the Enchanted Forest, ripping every inhabitant away to a town called Storybrooke, where the only happy ending is the Evil Queen's. This is until she adopts a child called Henry, who, on Emma's 28th birthday, visits her in Boston and reveals that he is her son. They then travel back to Storybrooke where Henry tells Emma that she is the only one that can break the Dark Curse. Emma reluctantly stays, not because she believes in the curse, but because she wants to keep her eye on Henry's adoptive mother who may or may not actually care about her son.

After breaking the Dark Curse in Season One, all of the fairytale characters still cannot go back to the Enchanted Forest and must deal with their own dual identities. With the introduction of magic into Storybrooke by Mr. Gold, the fate of the two worlds becomes intertwined, and new threats emerge in the form of Captain Hook, Regina's mother and two new people from our world with an agenda to destroy magic, or is it?

Their increasing power struggle with Pan continues in Storybrooke, which ultimately results in the complete reversal of the original curse. All the characters are returned to their original worlds, leaving Emma and Henry to escape to New York City.
