Barbara Stanwyck and Burt Lancaster star in William Keighley's 1950 production of Lucille Fletcher's classic drama of the bedridden, hypochondriac heiress who dials a wrong number and hears two men plotting a murder - her murder. "The client says he doesn't want her to suffer long.... He wants it to look like a robbery!" declares the unknown voice.
