For as much as the recent trailer and teasers have revealed, we're not certain exactly what overarching story 'Homeland' season 3 will build toward, given the literal and figurative shakeup at the end of season 2. A new behind-the-scenes video with Oscar-winner F. Murray Abraham and series star Rupert Friend may tease a new ongoing story, however, with plenty of action from the September 29 premiere!

The brief spot for 'Homeland' season 3 goes behind the scenes to watch filming of a new sequence from season 3 premiere "Tin Man is Down," in which Peter Quinn (Rupert Friend) goes on a deadly stealth mission that may have far-reaching consequences for the stoic agent. After breaking out in season 2, we'd expect Quinn to have an equal, if not larger part in season 3, based on the video.

Meanwhile, ‘Homeland’ season 3 picks up during the aftermath of the terror attack that decimated the US intelligence apparatus and prompted a global manhunt for the world’s most wanted terrorist, Nick Brody. As Carrie and Saul begin to pick up the pieces of their shattered professional and personal lives, they will be swept up in the political and media firestorm surrounding the terror attack and the subsequent search for Brody.

Along with the recent additions of ‘Iron Man‘ star Shaun Toub, Martin Donovan, Tracy Letts, Joanna Merlin, Nazanin Boniadi, Amy Morton, Lawrence Clayton, Sam Underwood, Gary Wilmes and ‘Game of Thrones‘ season 4 star Pedro Pascal, season 3 of ‘Homeland’ will see David Marciano (Virgil) and Diego Klattenhoff (Mike) stepping down as series regulars to take reduced roles, while Morena Baccarin will reprise her series regular role as Jessica Brody in spite of her husband’s absence.

While we wait for the September 29 premiere, check out the latest look at 'Homeland' season 3 above, and tell us in the comments what you think Quinn and the CIA will be up to!
