The citizens of Storybrooke are set to go on "high alert" as the Wicked Witch/Zelena's (Rebecca Mader) evil behavior reach an all-time high on Once Upon a Time.

Zelena 'Stands In The Way' Of Regina & Robin Hood Finding Love?

Zelena is set to go after Snow/Mary Margaret's (Ginnifer Goodwin) baby as part of her master plan on the next episode of Once Upon a Time. ABC released a plot synopsis Monday for the upcoming episode, which is titled Kansas.

The synopsis notes that Zelena will try and take the baby in order 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."

Regina Ready To Feel "Deep & Real" Love Again?

As this episode will be highly centered on Oz and its colorful cast of characters, there will be several guest stars. Among those guest starring in the episode are Sunny Mabrey as Glinda, Sharon Taylor as Witch of East, Karen Holness as Witch of North and Matreya Scarrwener as Dorothy.

As Enstars previously reported, the episode may even feature Dorothy "melting" the Wicked Witch, which is shown in the promo. It is not clear what effect this will have on the character going forward.

Once Upon a Time season 3 airs Sundays at 8 p.m. on ABC.
