A solar flare erupts and the EMP destroys all electronic equipment. The world has returned to a purely mechanical age.
The protagonist was once a talented player on the national orienteering team. Now he must rely on a broken military map and an ancestral mechanical compass to find the legendary "last radiation-free pure land" in a wasteland where electromagnetic radiation is raging and mutated creatures are rampant.
