The show follows antique and collectible pickers Mike Wolfe and Frank Fritz who travel around the United States to buy or ''pick'' various items for resale, for clients, or for their own personal collections. They originally traveled in a Mercedes-Benz Sprinter van and now a Ford Transit. Danielle Colby runs the office of Wolfe's business, Antique Archaeology, from their home base in Le Claire, Iowa, and more recently at a second location in Nashville, Tennessee. Fritz sells his acquisitions at his own shop and on his own website, Frank Fritz Finds, upriver in Savanna, Illinois. The men go on the road, not only following up leads that Colby has generated, but also ''free-styling'' - stopping at places that look like they might hold items worth buying. They also pick some places more than once.
