Body of Evidence is a psychological thriller film directed by Roy Campanella II and starring Margot Kidder and Barry Bostwick.

An unsuspecting nurse (Margot Kidder) fears her forensic pathologist second-husband (Barry Bostwick) may be the psychotic serial strangler behind a recent rash of grisly murders.

His wife, Carol (Margot Kidder), a nurse, organizes a neighborhood watch protection group because of the shocking slayings.

Every advantage he gets is lost because as the list of victims grows, the composite sketch changes with each new witness, as if the killer had the gift of always keeping one step ahead of the detective's investigation.

All the victims resemble her, and the clues appear to point to her second husband, the forensic police pathologist involved in the investigation whose increasingly bizarre behaviour seems to implicate him even further.
