Mad Men
Don Draper's (Jon Hamm) story comes to an end during the "Mad Men" series finale on Sunday, May 17 at 10 p.m. EDT on AMC. AMC

What will happen in the “Mad Men” series finale? Fans of the AMC series are going to have to watch to find out. Although most shows post brief episode descriptions of what viewers can expect, the synopsis for the finale, titled “Person to Person,” is one sentence and kind of ominous.

“The stories of Don Draper, his family and his co-workers come to an end in the series finale,” the synopsis on TV Guide teases.

With Betty (January Jones) learning she has terminal lung cancer in episode 13 and the constant Don (Jon Hamm) death theories, the "end" mentioned in the description could very well mean the arrival of the Grim Reaper. When fans last left off, Don was falling apart in Oklahoma, Pete (Vincent Kartheiser) was preparing to leave New York, Peggy (Elisabeth Moss) appeared to be entering a bad situation at work and Sally (Kiernan Shipka) learned Betty she wasn't going to seek treatment for her cancer. Although some plotlines have already potentially wrapped up, viewers still have a lot of questions they want answered.

The last episode of Season 7 airs Sunday at 10 p.m. EDT on AMC. For those dreading to say adieu to Don Draper and the rest of the gang, the network is airing a marathon leading up to the final installment. Meanwhile, AMC’s sister networks -- IFC, WETV, BBC America and Sundance -- are getting in on the fun with a tribute to the series finale. The TV listing for each channel at 10 p.m. EDT says, “We’re Watching ‘Mad Men’s Finale.” Clocking in at an hour and 15 minutes, viewers will get just a little more time with the dysfunctional ad man -- and it might be necessary to wrap up the story.
