In 2004, a man named Marvin Heemeyer wreaked havoc on the streets of Granby, Colorado in an armored bulldozer that would be dubbed the “Killdozer.” More than fifteen years later, a documentary about the incident is set to be released.

Titled “Tread,” the documentary tells the story of a man pushed to his breaking point that uses his welding skills to fortify a bulldozer with the goal of crushing those that he believes to have wronged him. Thus far, the film has been met with favorable reviews – 7.4/10 on IMDB. It features a number of real news clips, reenactments, and interviews.
