Mr. Gold and Regina send Ariel back to Storybrooke with an item that will allow Belle to locate a hidden artifact that could help take down Pan. But unbeknownst to them, two men have broken into the town with the intent to stop them at all costs.

Pan tries to convince Henry that he can save magic and Neverland; a young Rumplestiltskin receives a magical item that could give him a fresh start with his father.

The race to stop Pan is on as Henry's life hangs in the balance; with Mr. Gold's help, Regina decides to adopt a baby.

Pan's plan threatens the citizens of Storybrooke's joy over Henry's return; Snow and Charming spend their honeymoon searching for a mythical being that could stop Regina.

The residents of Storybrooke race to stop Pan from placing another curse on the town.

Hook goes to New York to help Emma regain her memories so she can help her fairy-tale friends and family.

Emma arrives in Storybrooke with Henry and reunites with her friends and family, only to discover that no one remembers how they were transported back--or the past year they had spent back in Fairy Tale Land. But Emma is sure that someone in town is responsible for this new curse and teams up with Regina in an attempt to uncover their identity. Meanwhile, in Fairy Tale Land during the past year, Regina, with the aid of Robin Hood, attempts to break into her castle, which has been overtaken by the Wicked Witch.

While Emma, David, Regina and Hook continue their search for the Wicked Witch, she, in turn, is planning a dark surprise for David. And Zelena's prisoner is powerless under her watch as she plots her next course of action against the townspeople. Meanwhile, in the Fairy Tale Land that was in the previous year, Prince Charming stumbles upon Rapunzel, who is trapped inside a tower, and must help her confront her fears in order for her to be free.

Neal finds himself back in Storybrooke and yearns for a way to reconnect with his son Henry, whose memories of his father are gone, while also trying to find his own father, Rumplestiltskin, whom he has just learned is alive but missing, and Regina discovers a possible connection with Robin Hood. Meanwhile, in the Fairy Tale Land that was over the past year, agonizing over the death of his father, Neal--with the help of Belle and enchanted candelabra Lumiere--attempts to find a magical solution to bring back Rumplestiltskin from the dead.

With Rumplestiltskin as her slave, Zelena challenges Regina to a fight to the death and shocks the Evil Queen with the reveal of their familial connection, and the town lays Neal to rest. Meanwhile, back in the past in the land of Oz, a jealous Zelena asks the Wizard to send her to Fairy Tale Land after discovering that she has a sister, Regina, and that Rumplestiltskin is training her to become a powerful force to be reckoned with.

Ariel returns to Storybrooke and pleads with Hook to help her find Prince Eric, who never returned to the town when the new curse was invoked. Emma agrees to let Regina teach her how to use magic so that she can help defeat Zelena, and Mary Margaret and David try to prove that they can be just as much fun as Hook is with Henry--who thinks they are boring. Meanwhile, in Fairy Tale Land during the past year, an angry Ariel confronts Hook over her missing Prince Eric, who she assumes was kidnapped and possibly killed by the swarthy pirate. But when Hook confesses that the Jolly Roger has been stolen and Eric is most likely the thief's prisoner, Ariel unknowingly provides him with a clue as to who the culprit

After Zelena steals Regina's heart, Regina casts a spell so that she can speak across the realms to her dead mother, Cora, to discover the truth about why she abandoned Zelena, and Belle stumbles across what Zelena's ultimate end game is. Meanwhile, in the Fairy Tale Land that was, young Cora is duped by a man claiming to be a prince and finds herself alone and pregnant. But a chance meeting with a real prince could lead Cora to the royal life she's always craved, but she must keep her pregnancy a secret or risk losing everything.

Zelena threatens to kill Henry if Hook--whose lips have been cursed by the Wicked Witch--doesn't proceed with kissing Emma, which will drain all of her magical powers away, and things begin to heat up between Regina and Robin Hood. Meanwhile, back in the Fairy Tale Land that was during the past year, Snow and Charming go in search of Glinda, the Good Witch of the South, to see if she can help them defeat Zelena, and the curse that will ultimately send the Fairy Tale characters back to Storybrooke is cast--but from an unlikely source.

With Mary Margaret in labor and due to give birth at any moment, the residents of Storybrooke go on high alert in an attempt to ensure that Zelena doesn't try to steal her newborn baby for use in her ultimate game plan to turn back time and change her destiny--while obliterating Regina's existence. Meanwhile, in the land of Oz of the past, Glinda tries to convince Zelena to fight her evil tendencies and join her and her sister witches as a protector of Oz. But the appearance of a young girl from Kansas could turn out to be her undoing.

In part one of the season three finale, Emma and Hook are pulled into Zelena's time portal and find themselves in the Enchanted Forest of the past, while Mary Margaret and David celebrate the naming of their son at a coronation in Granny's Diner.

In part two of the season three finale, Emma and Hook must be careful in their quest not to change anything in the Enchanted Forest of the past, lest they risk altering the lives of their friends and family--as well as their very own existence.
