The one-minute teaser shows Carrie up to her same old tricks, getting herself into trouble and nearly killed while trying to recruit informants.
One shot shows a framed photograph of Carrie holding a baby, which presumably means she either keeps her lovechild with Nicholas Brody, or is at the very least still involved in its life.
Mandy Patinkin and Rupert Friend are back for another season of the Golden Globe-winning drama.
No sign of the Brody family, though.
Season 4 of Homeland premieres Oct. 5.
