Communists take over the country and are fought off by old people with signs and microphones?
From Wikipedia:"The tone is going to be very intense, very much keeping in mind the post-9/11 world that we’re in. As ‘Red Dawn’ scared the heck out of people in 1984, we feel that the world is kind of already filled with a lot of paranoia and unease, so why not scare the hell out of people again? It was later revealed that the Chinese would be the invaders and they would be aided by the Russians later on."
The film is currently slated to take place in and around Spokane, Washington.
