Longtime friends Cody Allen (Perry King) and Nick Ryder (Joe Penny) 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 (Thom Bray), the team takes on cases, striving to help those in need. However, their investigations often cross paths with Lieutenant Ted Quinlin (Jack Ging), who's often none too happy with the crew.
