Lawrence Payne stars in this military courtroom drama. Major Keller (Payne) is a well-respected and decorated officer who is court-martialled after World War Two, accused of murdering of his commanding officer, Colonel Winch (Ralph Michael). It is also attested that Keller was in love with the Colonel's wife, Laura (Susan Stephen), and gave orders over the Colonel's head on the battlefield. To prove his innocence, Keller must rely on the evidence and testimonies given in court. But when he himself is the only witness, will his word be enough to win him his freedom?
