When Steven Armstrong tells his children he has fallen in love, he expects them to be happy that his life as a lonely, sixty-five year old widower is over. Instead their father's intended thirty-three year old personal trainer Charlene Hendricks is exactly the kind of woman they fear. Through marriage she becomes not only the stepmother to his three grown children, but their rival for their father's world class fortune. Suddenly an attack is made on her life. All the children are suspect, but which one has the best motive? Then a second attack backfires and mistakenly kills her husband, making the stepmother a wealthy heiress. Now, it is the children who accuse her of murdering their father. Only by finding the real killer can she prove her innocence.
