Plot

In Victorian England, philanthropic scientist Sir Hugo Cunningham is a member of a parapsychological society that studies psychic phenomena. As part of their latest investigation, the men have begun photographing individuals at the moment of death; done properly, the resultant photos depict a strange smudge hovering around the body. Though the society concludes that they have captured evidence of the soul escaping the body, Cunningham is sceptical.
