Longtime friends Cody Allen and Nick Ryder served together during the Vietnam war. Now that the war had ended, Cody and Nick start their own private investigation business and run it out of Cody's boat, The Riptide. With help from electronics guru Murray "Boz" Bozinsky, the team takes on cases, striving to help those in need. However, their investigations often cross paths with Lieutenant Ted Quinlin, who's often none too happy with the crew.
