"That all changes when a group of human rights missionaries search out the ‘American river guide’ John Rambo. When Sarah (JULIE BENZ) and Michael Bennett (PAUL SCHULZE) approach him, they explain that since last year’s trek to the refugee camps, the Burmese military has laid landmines along the road, making it too dangerous for overland travel. They ask Rambo to guide them up the Salween and drop them off, so they can deliver medical supplies and food to the Karen tripe. After initially refusing to cross into Burma, Rambo takes them, dropping off Sarah Michael and the aid workers.
