ABC released a new plot synopsis for the next episode of Once Upon a Time, titled Fall, which is set to air on Sunday, Nov. 30. By the looks of it, the anticipation of the upcoming spell will cause the show's characters to behave in a variety of ways.

"As the Spell of Shattered Sight approaches Storybrooke, Mary Margaret [Ginnifer Goodwin] and David [Josh Dallas] rally the residents to prepare for the curse while Belle [Emilie de Ravin] and the fairies work together on an antidote," the synopsis reads.

Meanwhile, Hook (Colin O'Donoghue) is still acting as a servant to Mr. Gold (Robert Carlyle), who has his own plan of escaping the spell.

Elsewhere, "Regina [Lana Parrilla] and Robin Hood [Sean Maguire] ready themselves for the worst while, with the help of a locator spell," Emma (Jennifer Morrison) and Elsa (Georgina Haig) continue their search for the latter's sister, Anna (Elizabeth Lail).

Back in Arendelle of the past, Anna and Kristoff (Scott Michael Foster) face danger of their own with their kingdom threatened.

On episode description alone this looks to be the most exciting episode of the season as everything comes to a head. It will be interesting to see if anyone becomes a casualty as they prepare for the dangerous spell.

Once Upon a Time airs Sundays at 8 p.m. ET/PT on ABC.
