The Cartwrights are scammed by brother and sister con artists. Joe is determined to catch them.
Trivia: This was Anthony Zerbe’s first and only appearance in the series. A one time Emmy winner, Zerbe has kept busy in Hollywood and on stage since the late 1960s, often playing villainous or untrustworthy characters, with his narrow gaze and unsettling smirk.
