Once they have applied the lotion, the chemist then releases his Devil Bats in the night, which kill his two former partners and three members of their families. A hot shot big city reporter gets assigned by his editor to cover and help solve the murders. He OBrien and his bumbling photographer Kerr begin to unwind the mystery with some comic sidelights. The mad chemist is, predictably, done in by his own shaving lotion, and by his own creationthe dreaded Devil Bat.PRC was a young studio when it planned to enter the horror film genre, which had been neglected by the major studios during 1937 and 1938. Lugosi was beginning a comeback when he signed a contract on October 19, 1940, with PRCs Sigmund Neufeld to star in the poverty row studios first horror film. The shooting of the film began a little more than one week later.
