"The Americans" is the most underrated show on TV. I didn't start watching it when it first started, it was a couple of years later, when I happened to see a rerun on TV. After watching about 10 minutes worth, I was completely hooked! It is a smart, realistic, dramatic thriller, although on the surface it seems pretty demure as it focuses on a family of 4 living in Washington, DC and their daily lives.
It turns out that the parents of the all-American family are actually Russian spies from the CBG, who infiltrated the U.S. as young adults, and have built their entire lives and family as Americans, while covertly working to advance Russian interests. The scenes where the parents/spies accomplish secret missions are thrilling and exciting, but the real drama comes where they maintain perfectly normal looking lives to the outside world, including hiding their true nationality and jobs from their two children.
In this particular episode, the father is stretched to his limits between the different women in his life. As part of his duties for the CGB, to compromise an American CIA employee, he has to woo her and actually become romantically involved with her, despite the fact that he has a very real wife - who knows all about his assignment. The parents actually have a real romantic relationship with each other, although when they became a couple years earlier it was all just for show as part of their duties as CGB members. Keeping his new "love" happy with a part-time relationship, when she wants to be with him every day as normal people do, while also keeping his wife and KGB partner assured that his interactions with the target are just an act, are almost too much for the father to bear, as they would be for anyone. Watching the dynamics between the couple and their family unit is fascinating.
