The fate of humanity is at stake when two races of giant humanoid plants, the good Sector-Bots and the villainous Generators, bring their war to Earth. The plants have the ability to shape-shift into both mechanical & organic objects as they seek the key to ultimate power. Only a human youth, Todd McConnell (Josh Hutcherson) can save the world from total destruction. (Plus, another thing, they aliens come form a planet named "Sectormetry".)
