An unlikely trio traverses a desert planet in search of a rumored lake- and the hope for a better life that it represents. Lernert travels across the barren landscape, digging through rubbish piles in an attempt to build a body for Susan, the robot head who hangs, unresponsive, from the back of his pack. The pair comes across Rola, a spirited twentysomething, who lacks survival skills but makes up for it with sheer determination. At first unwilling to travel together, the three-some navigate the harsh desert in search of a mythical water basin that can replenish their depleted resources and their will to continue.这四台光脑陈源和陈平兄弟俩可是找了近两百户人家才找来的，像这样的光脑，一般人都会当作贵重物品，就算无数变异动物进攻人类所有的乡村和城市的时候，那些人在逃跑的时候。一般也会带上他们的光脑。
