The Dudesons know something that most Americans do not -- their so-called friendly neighbor to the North, Canada, intends to invade American soil! In order to save America, the Dudesons train for battle through a series of physical tests and exercises, preparing them to become our first line of defense against the dreaded maple leaf. They have rubber bands snapped in their faces, get chased by attack animals, and swing down ropes into a wall - all in the name of training. Once trained, the Dudesons dig in on the front line, building and testing custom weapons and vehicles designed to thwart Canadian aggression such as an air-pressured cannon which shoots a huge amount of sharp, spiky bullets, attack Segways tested on an obstacle course and a battering ram using their heads as the ram. Finally, the Dudesons take the Canadian castle in their battle tank blowing up the Canadian headquarters.
