Mad Men
Don Draper (Jon Hamm) is back for the final episodes of "Mad Men." AMC

“Mad Men” will begin its long goodbye Sunday when the first of the final seven episodes of the series’ seventh and last season premieres on AMC. It has been more than a year since the midseason finale of Season 7, and fans may be having some trouble recalling how things left off last spring. Luckily, we have you covered with a recap of all the action from the last fans saw of Don Draper (Jon Hamm) and Co.

Here’s where all the key plotlines were in the midseason finale of “Mad Men” Season 7:

Sterling Cooper & Partners

The midseason finale ended with some pretty big changes coming to the firm. Jim Cutler (Harry Hamlin) had been pushing a vision throughout Season 7 that included touting the company’s new computer and elevating Harry Crane’s (Rich Sommer) status to partner -- but that plan also included getting rid of Don.

After Bert Cooper’s (Robert Morse) death, Cutler attempted to fire Don for crashing the Phillip Morris meeting, a breach of the contract stipulations he signed when he came back to work at the beginning of the season. Roger Sterling (John Slattery) stepped up to the plate to save his man. The senior account executive brokered a deal with McCann Erickson for the bigger agency to buy Sterling Cooper & Partners and maintain it as an independent subsidiary with Roger acting as president.

A big payday was in store for the current partners, but Don and Ted Chaough (Kevin Rahm) would have to sign five-year contracts as part of the deal. Don was happy to oblige to save his job, but Ted -- who had been considering leaving advertising for good -- was harder to convince. Eventually, Don gave Ted a convincing pep talk, and everyone got on board for the buyout.

Don And Megan

While it appears Don’s position at the firm is finally secure after a long period of uncertainty, his home life has collapsed once again. A phone call in the midseason finale revealed his marriage with Megan (Jessica Pare) was over. He had been in California two episodes before when the couple wound up having a menage a trois that Megan hoped would provide a spark to save their marriage. However, the bicoastal relationship seems to have finally run its course.

Peggy

Much like Don, Peggy has found success at work despite dissatisfaction with her personal life. She won the Burger Chef account in the midseason finale -- pitching instead of Don, who was worried he would be fired soon -- and finally may be gaining recognition as a true peer of the men in the office.

However, Peggy just turned 30 and has been lamenting how she does not have a husband and family like most women her age. Peggy confessed this regret to Don in episode 6 of Season 7, leading to the touching moment when they danced in her office to Frank Sinatra’s “My Way.”

Pete

Pete Campbell (Vincent Kartheiser) had been going back and forth between New York and California during Season 7, but his last trip to the Big Apple did not end well. After paying a visit to his kids and Trudy (Alison Brie), who was out on a date when he arrived, Pete finally realized his marriage was over when his wife coldly informed him that he “was not part of this family anymore.”

Meanwhile, his California girlfriend, Bonnie (Jessy Schram) -- who he had taken to New York under the pretense of a romantic getaway -- went back to the West Coast alone after tiring of Pete obsessing over work and pining over his family.

Everyone Else

There are plenty more storylines to follow when “Mad Men” picks back up.

Bob Benson (James Wolk) is headed to Buick after his failed proposal to Joan (Christina Hendricks). Speaking of Joan, the office manager-turned-partner may have chosen the wrong side after voting to dismiss Don in a partners meeting.

Meanwhile, Roger is an a great position after engineering the McCann buyout and apparently taking Cooper’s parting advice about being a leader.

Elsewhere, Betty (January Jones) seems to be at a crossroads in her relationship with Henry Francis (Christopher Stanley), whose political aspirations have caused some tension in their marriage.
