One part obsession, one part addiction, and an unending quest for adventure make Great Lakes surfers a truly rare breed.

Add 40-knot winds, 15-foot waves, and frigid temperatures to a storm-ravaged inland sea, and they'll tell you it's a recipe for fun.

Join filmmaker and surfer Vince Deur on a road trip around five Great Lakes to meet the surfers who have made surfing these stormy waters a way of life for nearly 40 years.

He is searching for the answer to the most obvious question: why they bother?

Why would a lawyer, an artist, a fireman, and a retired factory worker immerse themselves in such a harsh environment? What is it they are really looking for?

"Unsalted" is an adventure of the spirit. It makes a case for unwavering optimism in the face of adversity.

And it makes this landlocked group of surfers just a little better for it.
