"Homeland" season 3 trailer: Brody's back

Damian Lewis as Nicholas Brody on season 3 of "Homeland."

Showtime has just unveiled the official trailer for the third season of "Homeland," and there's a lot in this three-minute-long video to take in.

When we say a lot, we mean a lot. First of all, Brody's back -- but he's looking very different.

And that's not all. There's also glimpses of Saul testifying before Congress about last season's terror attack, Quinn wielding a gun, Carrie back in the mental ward and Dana snapping nude photos of herself (along with laying on her father's prayer rug).

It all ends with Saul telling a distraught-looking Carrie, "I am so sorry."

"Homeland" returns with new episodes beginning Sept. 29.
