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.反正夏草用腕仪联系了一个人后，几分钟后就帮陈源和苏云安排好了，说三天后就有一只飞船从伽蓝星到母星地球。然后第三天的时候，就有一辆外表很普通的飞车来把陈源和苏云接走。
