With sunken eyes and thin, bloodless lips in a cadaverous face, Kroll is a frightening and mysterious figure. After one of the trick-or-treating children is killed in a freak accident, Kroll disappears. It seems that he may have died in his bed. But Kroll's vengeful spirit haunts the town from beyond the grave. When a figure closely resembling Kroll returns to the town, dressed in the familiar overcoat and trilby, the inhabitants start to question what, if anything, lies in that churchyard burial-place...
