The Great Patriotic War is stumbling to a close, but a new darkness has fallen over Soviet Russia. And for a disparate, disconnected clutch of wanderers - many thousands of miles apart but linked by a common goal - four parallel journeys are just beginning. Gorych and his driver, rolling through water, sand and snow on an empty petrol tank; the occupant of a black airship, looking down benevolently as he floats above his Fatherland; young Andrey, who leaves his religious community in search of a new life; and Kharitonov, who trudges from the Sea of Japan to Leningrad, carrying a fuse that, when lit, could blow all and sundry to smithereens.
