Cover-Up transfers the metropolitan "film noir" milieu to a small Midwestern town.
Dennis O'Keefe plays Sam Donovan, an insurance detective, investigating the suicide of a policy holder. All signs point to murder, but no one in the victim's hometown is willing to cooperate with Donovan, least of all sheriff Larry Beat (
William Bendix). Local girl Anita (
Barbara Britton) breaks through the wall of silence and helps Donovan solve the mystery. Intriguingly, the action of Cover-Up takes place at Christmastime, with the tinselly Yuletide atmosphere providing stark contrast to the sordid murder story. ~ Hal Erickson, All Movie Guide
