An Allied plane containing top-secret equipment is shot down near Stalag 13. Hogan and his crew must retrieve the equipment without arousing the suspicion of Major Feldkamp (Ben Wright), a German engineering expert who is likewise nosing around the crash site. Somehow or other, the solution to Hogan's dilemma involves setting up a mobile gambling casino. Noam Pitlik rounds out the guest cast as Captain John Mitchell. First telecast on November 21, 1969, "The Big Gamble" was written by Laurence Marks. ~ Hal Erickson, Rovi
