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.

In an exclusive new clip from the episode watch as the head queen in charge, Sweetie (played by Roxy Wood), gives Letty—as Priscilla—a tour of the club, including the drag queens' dressing room that Sweetie promises Priscilla will never see because she will be stuck behind the bar serving drinks.

"All you need to worry about is how to make my Blue Curacao Slurpee Sour," warns Sweetie.

Like a professional drag queen, Sweetie makes sure the house bartender can correctly make her favorite drink.

In addition to Roxy Wood, other famous drag superstars make appearances in the episode including former RuPaul's Drag Race contestants Ginger Minj and Sharon Needles.

Will Letty become the club’s next drag star performer? 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 to win over the club's audience.

Watch the exclusive scene and you can catch the full episode when it airs Sunday, November 12 at 10/9c on TNT.
