Season Seven of The F.B.I. begins as federal agents Erskine (Efrem Zimbalist Jr.) and Colby (William Reynolds) set a trap for the extortionist. Serving as bait is pro football player Paul Talbot (Frank Converse), who cannot figure out who is sending him threatening messages, nor why. One thing is certain, however: Unless the Feds can locate Talbot's taunting tormentor, there's going to be a genuine "Sudden Death" during a championship game.
