Some years ago Spanish paddlers, Carlos Rodriguez and Carlos Ares, tackled a style of kayaking that was completely new to them. Drawn by the vast British Columbia wilderness, they sought out rivers to hone their ability to paddle long distances down whitewater rivers, carrying everything on board so they could spend weeks paddling and travel hundred of kilometers. Then they realized the possibility of going even further and for longer. They began to wonder about the biggest rivers, about the most remote and untamed arctic wilderness. Their target was obvious: the whole Mackenzie River by kayak. Official Selection National Paddling Film Festival 2015, Reel Paddling Film Festival 2015, 2nd Prize Setmana de Cinema de Muntanya 2015.
