100 Episodes Of Once Upon A Time Trailer Released

Heroes. Villains. New Worlds. Adventure. Love.

When Once Upon A Time returns next month, its Season 5 midseason premiere (titled "Souls of the Departed") will also be its 100th episode. To celebrate reaching the impressive milestone, ABC has released a new trailer that is nearly 7-minutes long.

Check out the trailer in the video below.

Emma, Regina, Mary Margaret, David, Robin, Henry and Gold arrive in the Underworld, on a mission to rescue Hook, only to discover that their search will be more difficult than they had anticipated. The inhabitants of the Underworld—all souls with unfinished business and many with quite personal vendettas—hound our heroes at every turn. Meanwhile, in an Enchanted Forest flashback, a familiar face from the Evil Queen's past returns to present Regina with the perfect birthday gift.

"Souls of the Departed" of Once Upon a Time will air Sunday, March 6 at 8PM on ABC.
