(Sequel of The Little Girl and the Graboids) Autobots and Decepticons have a new threat on their hands. Powerful creatures from space called Monstrum came to control the time, space and dimension. But, they can't get it unless they find the Key of Portals. It was a race against time, if the Autobots or Decepticons don't find the key first their lives are doomed, but they didn't know that there were many survived predacons on earth and a cybertronian femme hidden on earth's islands.
