The fifth season of "Homeland" is bound to introduce exciting changes for its viewers.

Entertainment Weekly reported that four new characters will be added to the Showtime political drama's lineup. Claire Danes' titular character, Carrie Mathison, will have a new love interest in the form of Jonas Happich (Alexander Fehling). He serves as the legal counsel of Düring Foundation owned by another new character named Otto Düring (Sebastian Koch), a philanthropist.

Düring Foundation is the private security firm where Carrie currently works for now that she has exiled herself from the CIA in Berlin, E! News wrote.

Season 5 will also feature Laura Sutton as Sarah Sokolovic, an American journalist who also works for the Düring Foundation. Miranda Otto stars as Allison Carr, the current Chief of Station in Berlin who's working directly under Saul Berenson (Mandy Patinkin), Entertainment Weekly added.

As reported by Entertainment Weekly, the official plot synopsis of the upcoming season reads: "Season five will pick up two years after Carrie Mathison's ill-fated tenure as Islamabad station chief. Struggling to reconcile her guilt and disillusionment with years of working on the front lines in the 'war on terror,' Carrie finds herself in a self-imposed exile in Berlin, estranged from the CIA and working for a private security firm."

Season 5 will pick up two years after the events of Season 4's finale, E! News noted. The entire season will take place in Berlin, with filming scheduled to begin in the capital this week, TV Line reported.

Its production in Germany marks "Homeland" as the first ever American TV series to shoot an entire season in the country, Entertainment Weekly added. Rupert Friend and F. Murray Abraham will also reportedly return to their respective roles in Season 5, but no one else from the previous season's cast will be reprising their characters in the upcoming season.

In this year's PaleyFest panel, E! News talked to showrunner Alex Carey about how these huge changes will affect Carrie's life.

"She has a new purpose and passion and I can probably tease that that's not going to last long," Carey told E! News. "She's going to have a relationship with German intelligence, and that's going to be one of the more interesting relationships this season because they are an ally, but it's a pretty rocky relationship regardless."

Co-showrunner Meredith Stiehm, however, insisted that Carrie will also have one positive aspect amidst these major changes - her daughter.

"She has come into her own with motherhood," Stiehm explained, as reported by the news outlet. "She's grown up. Instead of her being the problem child, she's now the mother, she's lost her father, and she's grown into the adult of the family. The rockiness of being a mother happens to a lot of women, and they get through it after a couple years so Carrie is in a good place now."

Season 5 will premiere on Showtime this fall.
