Three years ago, Earth was conquered by  force of robots from a distant world. They have one rule – STAY IN YOUR HOMES. Step outside and you get one warning before you’re vaporised by a massive robot Sentry, a crawling Sniper or a flying Drone.  If the vast Cube doesn’t incinerate you first.  But Sean Flynn is convinced that his father – a RAF pilot who fought in the war – is still alive. When he and his gang find a way to break the robots’ curfew, they take on the might of the Robot Overlords.
