Carrie (Claire Danes) will be all about work in the upcoming fourth season of Homeland - so much so that she is bound to "snap" at some point.

Homeland Back On Track For When Producers 'Conceived The Show,' Without Brody

Showtime released a new video Sunday in promotion of Season 4 of Homeland centering on Danes discussing Carrie's arc for the upcoming episodes.

"This season, Carrie is in Kabul. She's Station Chief there. She's kind of alarmingly high-functioning," Danes reveals in the video. "Her job is to perform drone attacks. She's all work all the time and she can't really engage on any other level."

Meanwhile, Carrie is also dealing with the loss of her lover Brody (Damian Lewis), who was hanged in Iran in the Season 3 finale. Not only did Carrie have to watch Brody being hanged, it was while she was carrying his baby in her belly. In Season 4, her family will be taking care of her baby while she is in the Middle East.

"It's very difficult being in the same space as her child," Danes explains. "It evokes Brody. The reality is that even those of us mothers who love our children have complicated feelings about it. Of course I want the best for Carrie and for her baby but I was eager to start exploring those ideas and we get to do that. Carrie is gonna get into very messy and dangerous territory. The band has gotta snap . . . It gets ugly."

This season of Homeland will be taking place mostly in the Middle East as production transferred from the U.S. to Cape Town, South Africa. As such, it will be quite different looking compared to the Brody years.

Homeland Season 4 is slated to premiere Sunday, Oct. 5 at 9 p.m. ET/PT on Showtime.
