Alex Tanner and his wife Patricia return to the United States after Patricia's father dies leaving her with a major stake in his global media empire. Alex is to take over while she stays home to raise their 18 month old son Billy. At a party given for him by the staff, a drunk newspaper columnist Danny Shine continuously badgers Alex saying he visited their home that afternoon and will have an interesting article in a few days time. Most people at the party think he's just being obnoxious so his assistant Greg Stanley angrily drives him home only to get there and find that Shine was dead in the sear beside him all the time. Stanley is charged with murder and Perry Mason agrees to defend him. Soon after however, the Tanners son is kidnapped, presumably to keep them from testifying about something at the trial.
