Matlock and Jerri head out to the beach with Billy and Cliff as Cliff prepares for an upcoming triathlon. Once there, Matlock is surprised to run into retired F.B.I. agent Ed Wingate, who is investigating a case of his own. While Matlock keeps himself busy occasionally running into Ed, Cliff throws himself into the competition, and Billy throws himself at Anita Montrose, the real estate agent who rented them the beach house they're staying at. When one of the people Ed is investigating is found dead, Matlock agrees to defend his old friend.
