Burgess Meredith guest-stars as Irishman Ownie Dugan. Suddenly striking it rich, Ownie decides to strike a blow against political corruption by turning the tables on his ex-partner Giblin (David Lewis)-but has he really turned over a new leaf, or is this just another scam? Featured in the cast are Judy Parker as Judy, Richard X. Slattery as McCoy and Don Haggerty as O'Neill. Cowritten by Bonanza star Michael Landon and William Jerome, "Six Black Horses" originally aired on November 26, 1967, then was given an "encore" presentation on July 16, 1972. ~ Hal Erickson, Rovi
