Robert Lansing guest-stars as Dundee, an ex-convict determined to prove that he spent five years in prison as the result of a frame-up. Ben Cartwright's efforts to help Dundee adjust to his new-found freedom are thwarted by the coldness of Dundee's wife Elizabeth (Fionnula Flanagan), and the casual betrayal perpetrated by the man's so-called friends. Written by Don Ingalls, this episode was largely filmed on location at Sonora. "Heritage of Anger" was first broadcast on September 19, 1972.
