The preview, mostly two extended clips focusing on Danes' CIA officer Carrie Anderson, lays out the "Homeland" premise pretty clearly: A military raid in the Middle East leads to the rescue of a long-missing American POW (Lewis). Anderson, though, has reason to fear that the hero may actually be part of an Al Qaeda plot. Paranoia ensues.
"Homeland" was adapted from the Israeli format "Prisoners of War" by Howard Gordon, Alex Gansa and original creator Gideon Raff.
Production on the 12-episode run of "Homeland" won't begin until this summer.
