Nothing but the Night plot
"This nightmare has already killed five people - now it's yours to live!"
Young Mary lives in a children's home of the Van Taylenfonds, after her mother Anna Harb (Dors), a convicted prostitute, was deprived of parental rights. Three administrators of the Van Taylenfonds have already been killed when a bus crashes on which the children of the home are on a trip and in which there are still three administrators. Mary ends up badly traumatized in the hospital. Former police officer Charles Bingham (Lee) joins Mary's doctor Peter Haynes and pathologist Sir Mark Ashley (Cushing) on the case.
