HISTORY's ratings record-breaker is back for another installment! In small towns, and along America's back roads, treasures are waiting to be uncovered - valuable relics from our history that are hidden in junk piles, buried in barns and stacked in garages. It takes experts to find them - and turn rust to riches. American Pickers follows two of the most skilled "pickers" - Mike Wolfe, owner of Antique Archaeology, and his business partner, Frank Fritz - as they hunt down objects with historical, collectible and pop culture value. Along the way, they meet people whose own stories open a window into American lives and history. AMERICAN PICKERS: VOLUME 4 proves there's no place Mike and Frank won't go in search of hidden treasure as they pick through the hills of Malibu, California, go to a backcountry Alabama auction, and go on assignment for William Shatner.
