The new Homeland trailer for season four of the hit show brings us drama. Lots and lots of drama. It's intense.

Between explosions and accusations of treason, the two minute long trailer shows Carrie Mathison (Claire Danes) in tears holding her baby, struggling over her decision of whether to abondon her young disabled child.

The trailer ends with Carrie whispering "I'm so sorry" before walking out the door, leaving her baby daughter in a room alone.

Season four will not see Sgt Brody return to the series after Damian Lewis announced his departure last year.

Brody's troubled daughter Dana will also not make an appearance in the forthcoming season, with showrunner Alex Gansa confirming she would "probably not" ever appear again.

"[Sgt Brody] was a character people loved to hate and hated to love. It's someone who we miss on set every day. And I can say that Dana Brody will not be back for season four," he told the Television Critics Association summer press tour last week.

Gansa also said the series will see Carrie become more mentally stable - until the next love affair leaves her feeling jittery and paranoid, that is.

"I think emotionally she has stabilised and the mental illness we have dealt with, she has now dealt with," he said.

Homeland begins screening its fourth season on Soho in New Zealand.
