Visions of lethal accidents and violent deaths govern April Stevenson's life, and both she and her mother go to extremes to prevent them from coming true. After a scandal that destroys her reputation, April moves to London to start a new life. Right on the first day in her new job, she has a vision that Stella, one of her colleagues, is going to be strangled. It is the first time she has seen a murder. Shocked and shaken, she informs the police. Inspector Terry believes her and unearths a vital secret buried in Stella's past, but a lethal chain of events has already been set in motion, and it seems that - once more - April's mother is involved.
