A series of brutal unsolved murders serves as the backdrop for the central narrative.
The movie logo features modified caps from Revue (Letraset, 1969): Compared to Colin Brignall’s original design, H and R lost the descending bits. In B, R and D, the open top left corner was closed and rounded off. E got the same treatment and was further calmed down by arms of equal length with vertically cut terminals.
