The drama that Emmy is mad about makes its long-awaited return to reveal what has become of haunted adman Don Draper (Jon Hamm) since he's proposed to young Megan (Jessica Pare).
Hint: Don's protegee Peggy (Elizabeth Moss) says his changed demeanor "concerns me."
As expected, the swinging '60s time period, with its backdrop of civil unrest, is marvelously realized.
The main attraction, though, is Mad Men's smoky swirl of characters: enigmatic, mesmerizing and sorely missed.
Catch the two-hour season 5 premiere this Sunday on AMC at 9/8c.
