The heroes of Storybrooke will do everything to stop Cinderella (Jessy Schram) from executing her deadly plan of revenge against her stepfamily in episode 3 of "Once Upon a Time" season 6.

Based on the trailer for the episode titled "The Other Shoe," Cinderella/Ashley Boyd will return to Storybrooke so that she can finally settle her unfinished business with her stepmother and stepsisters who tortured her in the past.

In the trailer, Cinderella's stepmother, Lady Tremaine (Lisa Barnes), asked her if she really believes that the prince will choose her over the other women at the ball. This seemed to anger Cinderella.

But it seems like Emma Swan (Jennifer Morrison), Hook (Colin O'Donoughue), and Henry (Jared S. Gilmore) are not convinced that Cinderella will really kill her stepfamily, and they will do everything to stop her from turning to the dark side.

Meanwhile, the trailer also showed that the lost story of Aladdin (Deniz Akdeniz) and his long-time love, Jasmine (Karen David), will also be featured in the upcoming episode.

Prince Charming (Josh Dallas), on the other hand, will try to find the truth about the revelation of the Evil Queen (Lana Parilla) about his father. Could Gold (Robert Carlyle) give him more information about the real reason why his father died in exchange for a favor involving Belle?

The Futon Critic lists the synopsis for the third episode of "Once Upon a Time" season 6, which reads:

"As Storybrooke continues to welcome the new arrivals from the Land of Untold Stories, families, friends and even long-lost enemies are reunited once again. When Ashley searches for her step-family, intent on settling their unfinished business, Emma, Hook, and Henry scramble to help her before it's too late. Meanwhile, Regina attempts to bribe Mr. Hyde (Sam Witwer) for information about how to defeat the Evil Queen and Snow (Ginnifer Goodwin) helps Dr. Jekyll (Hank Harris) find a suitable laboratory for his work. David makes a deal with Gold and delivers a message to Belle (Emilie de Ravin) in exchange for new information about his father. In flashback, Cinderella attends a ball and meets her prince."

ABC will air the third episode of "Once Upon a Time" season 6 on Sunday, Oct. 9, at 8 p.m. ET.
