'Mad Men' returns for season three

Get ready to go mad for season 3 of 'Mad Men'

Secret pregnancies, office affairs and the Cuban Missile Crisis—all in a day's work at the Sterling Cooper advertising agency. AMC's Emmy Award-winning series returns for a third season, which promises to tie up the loose ends left dangling at the end of season two while further unravelling more of the characters' dramatic lives.

Check out these photos for a first look at the action from the boardroom to the bedroom.

"Mad Men" returns Sunday, August 16, at 10 p.m. ET/PT on AMC.
