As a personal favor, Deputy DA Carol Baldwin (Kathleen Lloyd) asks Magnum (Tom Selleck) to investigate the alleged murder of a young mother, a death witnessed by the victim's little daughter. It is highly possible that the woman committed suicide and that the main suspect may be guilty of an even worse crime, but Carol hopes to spare the youthful witness the trauma of testifying. But how can Magnum get his job done now that he has been deprived the use of Robin Masters' Ferrari? ~ Hal Erickson, All Movie Guide
