When the Mad Men mid-Season 7 Finale episode airs this Sunday, Don Draper's life will never be the same when his estranged wife Megan will possibly be killed in a plane crash.

This week's episode will start at 10:00 p.m. ET on AMC and can be viewed online through live stream via the link provided below.

After Don breaks his promise that he and his wife will move to Los Angeles together, an infuriated Megan leaves him and New York behind as she seeks to continue her acting career in Hollywood. While she is onboard a plane with Pete's girlfriend Bonnie, it appears the plane will have severe turbulence.

Here is the outline for the episode:

"Don is troubled by a letter; Peggy may seek a new future on a risky venture; Roger receives a phone call; Pete and Cutler butt heads," according to the official summary.

In the upcoming cliffhanger episode, Don goes into a drinking binge after he leaves Sterling Cooper Draper Pryce advertisement agency, the company he gave his heart and soul to since the series debut in 2007.

In a recent interview, John Hamm (who plays as protagonist Don Draper in the long running series) hinted that the series will not have a happy ending when the series finale airs next year.

"I'm not going to say I wish it wouldn't end," said Hamm to the Huffington Post, in reference to how the series will end in the future. "Because everything has to end, but it is what it is. We're going to have an emotional journey once we wrap it up. We'll walk away and lock the door."

Hamm also revealed how difficult it would be when he no longer has to play Draper after the drama series concludes.

"It's been a big, big, big part of my life. I've got a lot of really good friends in the cast and crew. It's going to be tricky [to see it end]," said Hamm.
