A drought wreaks havoc on the normally abundant truffle crop in Falls City, Oregon; a low supply promises a high price per pound of truffles.

Oregon's truffle kingpin Justin Anderson acquires 90,000 more acres to dig but with more land comes more risk of poaching. Richey Maxfield sets up shop in Old Faithful and Terry and Roy take a trip to a secret spot along the Willamette River.

An early freeze sweeps through Oregon, threatening the remainder of an already sparse crop of truffles.

While trying to move truffles on the black market, Ty and Levi run into trouble, and must race against time; Richey sets up a booby trap; Justin confronts poachers.

The men prepare for a last hunt to salvage the season; Ty and Levi go into the underworld to make up for losses; Richey goes all-in; Justin makes a push to double his profits.

There is a fortune buried deep in the ancient forests surrounding the small town of Falls City, Oregon...but only a few men know how to find it. For 10 weeks every year, they are on the hunt for one of the most expensive foods in the world, a delicacy that the Roman emperor Nero dubbed the Food of the Gods: black truffles. For the foragers of Oregon, truffles are more valuable than gold. For the first time ever, we've gained exclusive access to a secret underworld of foragers and backwoods entrepreneurs. This season, an historic drought ravages Oregon, choking off the usually abundant wild black truffle crop, and winter arrives early. With the truffle supply at an all time low, the price is predicted to hit an all time high. With increased competition between the foragers and even more diggers seeking riches, the truffle men of Oregon will be pushed to their limits to survive. Written by Discovery
