The Gas Monkeys race to finish their Buick Indy Racer for a deep-pocket client. Next, a collector wheels and deals for Richard's 1975 Datsun 280-Z.

A customer is found hiding in a refrigerator. Ashley swears he was waiting for closing time to sneak out and rob them. She demands they hire overnight security, but Les squashes the plan. It's a move he may regret come nightfall.

Les is handing out the hundreds for a parade of items that Seth and Ashley claim are worthless. When the kids reveal his backroom piled sky-high with everything from Pontiacs to prosthetics Les is flat out busted. Can he make a sale before the end of the day and go from hoarder to hero?

Les is presented with a jar of gold powder that could be worth thousands, but Ashley is convinced it's useless. An explosive acid test reveals its true nature. And later, Ashley is eating her words and Les is crying like a baby.

A conflict over a fake receipt turns into a full-blown war at the window. But when Les tries to call the customer's bluff, she comes back with a Motor City lawyer who could land Les in hot water. But Mr. Gold has a big surprise up his sleeve.
