The end of Mad Men is nigh, with the last episodes of the series' seventh and final season set to premiere in April on AMC, and the network released a teaser trailer for the season today.

The 30-second teaser expands on the promotional photos AMC released earlier this week featuring the Mad Men cast at a party. The trailer, called "The Party's Over," doesn't look like footage from any actual episodes. Instead, it sets the mood decidedly in the 1970s, with Diana Ross' "Love Hangover" playing over shots of Don, Peggy, Joan, Roger and the rest of the ensemble cast decked out in the warm colors of the new decade.

The first of the last seven episodes of Mad Men will premiere April 5 on AMC.
