Downton Abbey's Michelle Dockery is trading Lady Mary's corset and gown for a lacefront and heels on an upcoming episode of her TNT drama, Good Behavior: On the November 12 episode, Dockery's character, ex-con Letty Raines, pulls a Connie & Carla—infiltrating a drag club as "Priscilla McCall" so she can steal half-a-million dollars and stay out of prison.

But when Priscilla's hired as the new bartender, she's got to deal with RuPaul's Drag Race stars Ginger Minj and Sharon Needles. How does she get the queens on her side? By serving them free alcohol, of course—the quickest way to a drag queen's heart.

Will Letty become the club's next drag superstar? Nothing ever works out smoothly on Good Behavior, but let's just say that Betty Who plays a role in helping her with her plan.

Below Dockery and Good Behavior's out showrunner Chad Hodge talk about Letty's most outrageous disguise yet.

Hodge hasn't been afraid to push the envelop with queer content on Good Behavior: Last season, Letty walked in on her old flame, Kyle (Justin Bruening) bent over a desk and getting pounded by a mystery hunk (Caleb J. Spivak).

The drag-tastic episode of Good Behavior airs November 12 at 9/8C on TNT.
