A young woman hands her baby to a perfect stranger - the daughter of Delia Wainberg, a lawyer in the same firm as Joanne Kilbourn's husband - and disappears. One close look at the child suggests a family relationship, and soon the truth about the child Delia gave up for adoption years ago comes out. The boy must be Delia's grandson, but then his mother is found dead, sexually assaulted and murdered. Not only is there a killer on the loose, but the dead woman's partner is demanding custody of the child.
