The Cradle Will Fall(1983)

Kathy DeMaio checks into the hospital and thinks she sees a body being loaded into the trunk of a car. When the body turns up later and the murderer, Dr. Highley, thinks that DeMaio can identify him, her life is put in jeopardy. Originally made for television and adapted from a novel by Mary Higgins Clark, the interesting twist to this thriller is that several cast members of the daytime soap opera "Guiding Light" play those same roles here.
