Lizzy Caplan is returning to Showtime.

The pay cabler has acquired a BBC miniseries headlined by the former Masters of Sex star.

Titled Ill Behaviour, the project is described as a six-part comedy thriller that centers on Joel (You're the Worst star Chris Geere), who is determined to save his friend Charlie (Da Vinci's Demons grad Tom Riley) when Charlie announces he is stopping chemotherapy for his cancer in favor of a more natural treatment. Newly divorced, Joel moves in with Charlie, who sets him up on a date with Nadia (Caplan), a doctor who also happens to be a raging alcoholic.

The series hails from writer Sam Bain (Peep Show) and director Steve Bendelack (Friday Night Dinner). Iain Morris and Damon Beesley executive produce for Fudge Park Productions. BBC Worldwide handled international distribution rights for the project.

"Ill Behaviour is a brilliantly written series from the mind of Sam Bain which explores how far friends will go to protect each other, whilst blurring the lines of what’s right and wrong," Morris and Beesley said. "It features nuanced and honest performances from the cast across the board and we can’t wait for audiences in the U.S. to see this hilarious comedy thriller." 

The series will debut stateside Sunday, Nov. 13, at 10:30 p.m., and will be paired with the freshman comedy SMILF

Caplan earned an Emmy nomination for her role as Virginia Johnson in the Showtime period drama Masters of Sex, which ran for four seasons before wrapping in 2016. Her other credits include Party Down, The Class and Freaks and Geeks. 

Geere, who can currently be seen in season four of FXX's You're the Worst, is also known for his work in EastEnders and Waterloo Road. Riley's other credits include Doctor Who.

This is the latest partnership between Showtime and the BBC, which also co-produced on the Matt LeBlanc comedy Episodes. (However, BBC did co-produce the most recent fifth and final season, which is set to wrap Sunday, Oct. 8.)
