Director Jon Cohrs set out on an unusual journey. What if Lewis & Clark were around today and they explored the Hackensack river? This intriguing documentary takes us on that trip to get an unusual vantage point on both this post-industrial waterway and the post 911 reality in America. Deftly edited “Back Water” takes us along for the ride to explore with the mixed crew of 8. The cook, the trapper, the sound man along with the director and others share the experience .
