Tread

Tread explores the events that occurred on June 4, 2004 that nearly destroyed the small town of Granby, Colorado. Marvin Heemeyer was a master welder pushed to breaking point by members of the community whom he believed had wronged him. His act of revenge was one that nobody saw coming.

Heemeyer loaded a 61-tonne bulldozer with steel and concrete and armed it with powerful firearms. He set out through the town, destroying a number of homes and businesses and resulting in seven million dollars’ worth of damage. This act of terror lasted for two hours, as police were unable to slow the machine down. It finally ended when he took his own life by shooting himself.

Tread investigates what drove Heemeyer to this violent rampage and takes a deeper look into his perspective throughout this destructive act of revenge. The documentary tells the real story behind his motives.
