Convinced that one prisoner has turned by Al Qaeda and prepares for making a horrible attack, Carrie Mathison, a CIA operation officer, who has done an illegal mission in Iraq, that brings terrible for her and leads her to be sent into another section of facing terrorism, has to return back to the world she left behind.
I'm being incredibly inartistic, but I think that she - Carrie Mathison - is such a compelling character, and I think her journey is part and parcel with what Homeland is about, juxtaposed to the world and what is happening in the world currently.
Carrie gets pulled back into the twisted espionage world of Homeland in the darkly tense opening hours of season five, and if you ever gave up on the show in the past, you'd be doing yourself a favor in joining her.
Season 5, which picks up more than two years after last season's boom-clap climax and measured denouement, offers neither the candy-hued crazy of Season 3 nor the tightly plotted thrills of Season 4, but rather something more ruminative and sedate.
As you watch Carrie battling her demons once again while Peter quietly and efficiently goes about his business, you can see a graceful and profitable way for the show to avoid overstaying its welcome.
