This isn't your grandmother's antiquing. The American Pickers are on a mission to recycle America, even if it means diving into countless piles of grimy junk or getting chased off a gun-wielding homeowner's land. Hitting back roads from coast to coast, the Pickers earn a living by restoring forgotten relics to their former glory, transforming one person's trash into another's treasure. The show follows the team as they scour the country for hidden gems in junkyards, basements, garages and barns, meeting quirky characters and hearing their amazing stories. If you think the antique business is all about upscale boutiques and buttoned-up dealers, this show may change your mind – and teach you a thing or two about American history along the way.
