Telluride, Colorado's Mountainfilm is four days out and counting. To continue our trailer-a-day trend, here's Kadoma, a film from whitewater kayakers and filmmakers Ben Stookesberry and Chris Korbulic. Kadoma tells the story of their ill-fated kayaking expedition to the eastern Democratic Republic of Congo, where trip leader Hendri Coetzee was killed by a crocodile in December 2010. Outside's Grayson Schaffer wrote a detailed account of the expedition for our March cover story, Consumed. Read it for more information on why Coetzee, who was the first to paddle some of Africa's hardest rivers, was among the world's most accomplished kayakers. Watch the (tense) trailer above.
