Dave's crew thinks he's nuts when he decides to rip up his new property, a former jewelry store and workshop, but he's convinced there's gold hidden in and under the carpeting. Elsewhere, Diego gets a lead on a vintage electronics dealer and brings his buddy James along, expecting to find the mother lode in vintage motherboards. Meanwhile, Rich's search for precious metals leads him to an antiques dealer selling off an entire storage unit full of items from someone's estate.
