Homeland tells the story of Carrie Mathison (Danes), a bi-polar CIA officer who plays by her own rules. At the end of last season Carrie, pregnant with the late Brody's (Damian Lewis) baby, along with her mentor Saul Berenson (Mandy Patinkin), brought a significant and much-needed win for the agency and country at large. Along with Danes and Patinkin, Emmy nominee Rupert Friend will return for Season 4, along with Nazanin Boniadi, who was recently promoted to a series regular.

Homeland tied for the most wins of any program at the 2012 Emmy Awards, honored with six wins including Outstanding Drama Series, Outstanding Writing for a Drama Series, and Outstanding Lead Actress and Actor in a Drama Series; and garnered 11 Emmy nominations in 2013. Additionally, Homeland has been awarded Golden Globe Awards, SAG, Peabody, Television Critics Association, AFI and Critics' Choice Awards. The series was developed for American television by Alex Gansa & Howard Gordon, and based on the original Israeli series "Prisoners of War" by Gideon Raff.
