As 'Homeland’ season five is set for an official premiere in October, the hit series’ producers recently dropped hints on the possibly storylines for Carrie Mathison and Saul Berenson, the series' main characters.

While it has been confirmed that things will be kept more tense and interesting between them and among the rest of the characters, the upcoming season will be putting forward the issues related to terrorist group ISIS.

'Homeland' season five will present its characters as they try to address the new threat from the group, Showtime Entertainment President David Nevins said to TV writers on Tuesday.

As already known about the fifth season of ‘Homeland,’ the story will take place three years after the events that happened in 2014.

As a means of giving the award-winning series a rebirth that is much needed since th fourth season was unveiled, the show's central character, played by award-winning actress Claire Danes, decides to live in seclusion in Berlin, Germany. As pointed out by producerAlex Gansa, the new location is a "center for the surveillance refuseniks."

Estranged from the CIA, “Carrie is out of the intelligence business when the season starts and she finds herself in Berlin. It's a center for dissidence,” Gansa explained. “That's where hacktivists go because German privacy laws are so strict. It's hard to have surveillance on people there."

Carrie's other challenges will include trying to take the helm in the uptight relations between the U.S. and Vladimir Putin's Russia.

For the first time in ‘Homeland’ history, viewers will get to have a glimpse of the former CIA agent in an entirely domestic role with radically different obligations at home and at work.

Looking into Carrie’s new career, this erratic jump becomes a talking point among her former colleagues in the U.S.

With her mentor and friend Saul being assigned once again as the director of the CIA, he believes Carrie’s tasks are considerably in opposition to her former values. By employing herself for a radical individual rather than in a larger agency, Gansa states that her character is being deemed as a traitor to her country.

'Homeland' has often sought to address contemporary issues, and Nevins pointed out that this season will include storylines that could shed light on the Charlie Hebdo massacre as well as the privacy issues brought on by Edward Snowden.

During the past seasons, Carrie was shown dealing with Mideastern rebel groups and resolving difficult concerns, such as the divided attention of numerous officials in countries like Pakistan.

Although there had not been an announcement on 'Homeland' being renewed for season six, Nevins shared his sentiments about the upcoming season, saying that he thinks the fifth installment will feel "fresh" and that he expects it will stay put on Showtime "for many years to come."

Showtime’s ‘Homeland’ season five is set for an official premiere on Oct. 4. A teaser trailer for 'Homeland' season five can be viewed below.
