The court martial of major keller (1961)

Lawrence Payne stars as Major Kellor, a well respected and decorated officer who is being court-martialled for the murder of his commanding officer Colonel Winch. The facts of the case are shrouded by the mayhem of war and the effects that fear, pressure and duty have upon a soldier. Did the Major covet the Colonel's wife? Was the Major ambitious and kill Winch to secure a promotion? Or had the Colonel cracked under the pressure of an illustrious battle career? To prove his innocence Major Keller must rely on the evidence and testimonies given in court, however when he himself is the only witness, his word may not be good enough to win his freedom.
