The next episode of Once Upon a Time is titled Sympathy for the De Vil and centers on Cruella de Vil (Victoria Smurfit) and her villainous plans. She kidnaps Henry in the new episode, as teased in the plot synopsis for the episode.

"In Storybrooke, Regina gains leverage to keep Gold [Robert Carlyle] from interfering with her plan to rescue Robin [Sean Maguire], but her trip to New York takes the backseat when she and Emma [Jennifer Morrison] learn that Cruella has kidnapped Henry," the synopsis reads.

The episode will also feature a flashback to Cruella's past, which will help to explain how she became who she is today.

"In fictional 1920s England, viewers meet a young Cruella, whose oppressive mother uses her Dalmatians to terrorize her daughter," the synopsis says. "Cruella is confined to her mother's attic until a mysterious stranger arrives and empowers her to challenge her captor."

There will be many guest stars in this episode, including Patrick Fischler as Isaac, Kristin Bauer van Straten as Maleficent, Anna Galvin as Madeline, Milli Wilkinson as Young Cruella, Morgan Tanner as Dancer #1, Scott Augustine as Dancer #2, Tony Giroux as Dancer #3, Michelle Dawley as Dancer #4, Kelly Konno as Dancer #5, Julia Harnett as Dancer #6 and Jolene Bothwell as Dancer #7.

It remains to be seen if Regina and Emma will find Henry and return him safe, but either way it should be fun to see the two characters teaming up again.

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