The nuclear materials Ulof needs to better his invisibility machine are extremely rare and kept under guard in government facilities. Krenner arranges the prison break of notorious safecracker, Joey Faust (Douglas Kennedy), to steal the materials he needs. Of course Faust will do the jobs while invisible. Krenner offers Faust money for the jobs and Faust expresses his grievances against working for him. Faust tells him that he’ll sing like a canary if he’s returned to prison. Krenner tells Faust that he’s wanted alive or dead. Faust reluctantly complies. However, when he meets Faust’s woman, Laura Matson (Marguerite Chapman), he slowly charms her into a double cross.
