FALLING SKIES UK focuses on the resilience of the survivors and their determination to maintain their humanity when all else has been destroyed. It is a tale of endurance, commitment and courage in which everyday people are called upon to become heroes. They may be outmatched, outnumbered and outgunned, but nothing can beat the human spirit. Most of all, the series is about the ties that bind people together in the most difficult of circumstances.The aliens in the series are mighty, mysterious and merciless. They are highly intelligent and use military-like tactics, which makes them an overwhelming force against the few survivors that remain. There are three types of alien threat that the human survivors have named Skitters, Mechs and Overlords. The spider-like Skitters are simultaneously vicious killers and a nurturing family for the captured children. The deadly, robotic Mechs are controlled by the Skitters and pose the biggest risk on the ground, as their advanced weaponry and armor can take out many fighters without taking a dent. The Overlords are still a great mystery, but appear to be the real ones in charge of this invasion. The aliens control captured children, like Kevin’s son William, through bio-mechanical harnesses but have yet to reveal their ultimate plan for them.
