Businessman Robert Kraft (Richard Boone) takes over for a year as the trustee manager of the Immortal Hills cemetery as part of his community duties.
Kraft idly sticks a couple of black pins (meaning “occupied”) in a large wall map of cemetery plots instead of white pins (“vacant”).
The two owners of those cemetery plots both die in a horrific traffic accident.
He does it again and the next man drops dead of heart failure.
Kraft believes he has been given a supernatural power to inflict death with the pins and becomes beset with guilt until he’s verging on a complete breakdown.
Most of the film is a particularly effective exercise in low-key terror, and it’s a pity that the ingenious scriptwriter (Louis Garfinkle) couldn’t provide a more satisfactory ending. The climax really lets the film down.
The cemetery scenes were filmed at the Rosedale Cemetery in Los Angeles.
