Fiend Without A Face (1958)

In rural Canada, an experimental atomic powered radar project helmed by U.S. Air Force Major Jeff Cummings has irate local farmers taking to the fields in protest. But when townspeople's bodies start turning up minus their brains, it's up to Cummings and local beauty Barbara Griselle to discover whether it's the airbase's atomic reactor or Barbara's boss Professor Walgate's psychic research experiments that are behind the grisly deaths.
