The multi-award-winning US drama Mad Men returns to RTÉ Two next Tuesday (September 17) for its sixth season.

Starring Jon Hamm as flawed advertising executive Don Draper, Elisabeth Moss as the ambitious Peggy Olsen, and Vincent Kartheiser as oily account executive Pete Campbell, the show picks up in December 1967.

In the season opener, Roger Sterling (John Slattery) gets bad news about his mother, while Peggy becomes increasingly dictatorial at her job in Cutler, Gleason and Chaough.

Back at Sterling Cooper Draper Price, Ken Cosgrove (Aaron Staton) becomes suspicious of the intentions of mysterious brown-nosing junior accounts man Bob Benson (James Wolk).

And while Betty (January Jones) takes in a house guest for Yuletide, Don spends Christmas in Hawaii with Megan (Jessica Paré).

Mad Men returns to RTÉ Two on Tuesday, September 17 at 11.00pm.
