Far removed from the shiny exteriors and fully stocked garages of big-money chop shops, hard-core motorcycle enthusiasts the Sinners carve out their own methods of custom bike design. This intimate 2005 documentary follows Kutty Noteboom, punk rocker and chopper craftsman, his buddy Rico and the rest of the Sinners as they rummage junkyards and build machines from the ground up with a raw and unapologetic passion for choppers.
