Falling Skies Season 3 Episode 2: Collateral Damage
5 second plot: The Espheni (the bad guys) are going to attack on a large scale. The humans respond by destroying their power source. Without power, they can't charge their war robots. The result strangely enough is that they will still attack. Even on a bigger scale. Duh.
5 second review: All the aliens have got flashy names now. That's peculiar. But cool. The development with the baby is very interesting. I like that stuff.
