Claire Danes in 'Homeland' season two trailer - watch
In the clip, Belgian choir Scala & Kolacny Brothers's cover of 'Every Breath You Take' is played in the background while the focus is on Homeland regulars Claire Danes and Damian Lewis, with quick shots of new cast members like Rupert Friend.
Showtime said in a statement: "As we begin season two, Carrie is no longer with the Agency. The disgraced ex-officer is on the slow path to recovery, after her manic flight in season one nearly crashed Brody's political career…
"Meanwhile, Brody is several months into his inaugural term as a freshman Congressman, and finds himself buffeted daily by competing agendas. With every lie he tells, the walls around him close in a little tighter…"
Back in July, Danes also offered hints of what to expect from her character in the upcoming season.
"She gets her mojo back, but it takes some time," she said. "I think she's a little less paranoid, a little less high-strung."
Season two of Homeland premieres on September 30 on Showtime.
