Down Below (also known as Hell), chaos reigns. Junior devils, Ishtar and Scabrous, have failed in their efforts to control the life of their patient, Jack. As punishment, they are transformed into hounds for mortal combat. To escape and avoid execution for their failures, these devil dogs seek refuge in the Harrows. Since Noah's Flood, the Harrows has been a refuge for those excluded from heaven and hell. In the desert lands of the Harrows, a spring flows at the place where a mysterious itinerate Jewish preacher appeared long ago. The occupants of the Harrows are warned not to drink from the constantly flowing spring. In 1979, Jack arrives in isolated West Berlin to fulfill his ongoing responsibilities as executor of his murdered wife Sarah's estate.

Intent on repatriating Sarah's collection of Nazi stolen art, Jack is distracted by a former lover, Aydin. Aydin flees from the clutches of her crazed uncle, who, intent on effecting an honor killing, has killed Sarah by mistake. In West Berlin, Jack must stay a step ahead of criminal forces intent on seizing Sarah's art while dealing with Aydin, who has machinations of her own.
