Teacher Jay Griner, aka Mr. G, saved his hometown from the Ditchmen invasion. Then with his not-so-late wife, Amy, they saved the town once again from the combined forces of the government (EPA), the media, defense contractors, and Silicon Valley.

This time, they must use a new and improved Ditchman to withstand the retaliatory efforts of defense contractor Stan Bando, along with his version of a Ditchman called Dirt Cake, and save their hometown for the third time.
