Seeking adventure, a couple, Ernst and Emilie, embark on a trek across the Himalayas, from Nepal into western Tibet. After a clandestine mountain crossing at the source of the Brahmaputra River, the two lost explorers find themselves destitute with no map and meager supplies. Suddenly, they are captured by a bedraggled patrol of outcasts from the Chinese Army. Their trip turns into a wild odyssey as they become 'prisoners" of this ragtag group of wacky characters. "Dripping wet and shivering, we found refuge in a shack adjoining the collection of drowning huts from which we had escaped. It turned out to be the Tibetan version of an inn, a dank room with a dirt floor, one shaky iron table and two crude benches. Rain drummed on the corrugated tin ceiling and pissed through holes which made us, as soon as we sat down, keep shifting our bench to evade the worst waterfalls and the largest puddles. The tottering keeper, a clearly inebriated old man pointed in our Tibetan phrase book at 'no food" and at 'no drink." 'Nga amerika nay yin," Emilie said.
