Combat veterans Aaron Howell and Russell Davies, injured in war, come together for another mission as they guide blind Navy veteran Lonnie Bedwell on his third trip through the Grand Canyon. Over a 14 day river trip they battle more than 80 powerful rapids, screaming directions to Lonnie the whole way. Throughout the journey they remember their past experiences and learn that negotiating the rapids of life is as simple as forming a team, kicking out in the current, and finding a line through the chaos.
