Two friends are midway on a canoe trip down the Danube River.

 They discover the corpse of a peasant in the woods. When they return to their canoe the oars are missing. As night sets in, a general creeping sense of unease permeates the wild and rural setting…

Most ominous are the masses of dense, desultory, menacing willows, which “moved of their own will as though alive, and they touched, by some incalculable method, my own keen sense of the horrible.”
