Psychologist Charles Marlowe (Lee) invents a drug which will release his patients' inhibitions. When he tests it on himself, he becomes the evil Edward Blake, who descends into crime and eventually murder. Utterson (Cushing), Marlowe's lawyer, believes that Blake is blackmailing his friend until he discovers the truth.

It stars Christopher Lee as the doctor and his alter ego, and Peter Cushing as Frederick Utterson, a central character in Stevenson's original story. Mike Raven and Susan Jameson also star. It was photographed by Moray Grant, with music by Carl Davis.
The film performed poorly at the box office. Time has been kinder to the film and it is now seen as a very faithful adaptation with Drew Hunt of Chicago Reader listing it as one of Christopher Lee's five best roles.
