It's about two KGB spies (Soviet Union/Russian spies) who were sent to Washington DC to live in America as sleeper agents during the Cold War in the 1980s. The plot is one of the more intriquing ones I've seen on TV lately. There's only been one episode but after a somewhat slow start to it, it got pretty interesting. I'm not 100% on it yet so I'm going to watch tonight and see how it goes.
