The morbid pathology of a schizoid personality with paranoid delusions charts Gil Gray' course, past and present, with his current escape from a mental hospital. Murder to get his picture leads to more plans for murder to get the negative, and photographer, Joan Markham, looking for the best in everyone, is his prey. Security with her, hatred of those who are part of her life, an insane fear of cats, more murder and Gil's fantasy world collapses under the reality of police and the guy who loves Joan. A sick mind under a slick -- if disturbing -- treatment.
