VIDEO: Sneak Peek - 'The Price' Episode of ONCE UPON A TIME

On the next episode of ABC's ONCE UPON A TIME titled "The Price", when vengeance descends, an evil queen must conjure her most startling transformation ever. The episode airs Sunday, October 4th at 8 pm/ET on ABC. Get a sneak peek below!

Welcome to Storybrooke, Maine, a small town that probably won’t show up on your GPS, but it’s a magical place to visit. Reality and myth merged after Emma broke Regina’s curse, which had deprived the fairy tale characters of their memories and trapped them in our modern world. When they finally regained their identities, our heroes were dismayed to discover that they weren’t transported back to Fairy Tale Land. To make matters worse, Rumplestiltskin – aka Mr. Gold – decided to escalate his power struggle with Regina by introducing magic into the town. But this is our world, and magic always has a tendency to yield unfathomable consequences.

“Once Upon a Time” returns to the ABC Television Network for its fifth season and master storytellers Edward Kitsis and Adam Horowitz (“Lost,” “Tron: Legacy”) invite everyone to join Emma Swan, Snow White, Prince Charming, The Evil Queen, Hook and all the other resident fairytale characters as they cope with Emma’s new role 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…
