The wife of marshal Matt Morgan is raped and murdered. The killers leave behind a distinctive saddle, that Morgan recognises as belonging to his old friend Craig Belden, now cattle baron in the town of Gun Hill. Belden is sympathetic, until it transpires that one of the murderers is his own son Rick, whom he refuses to hand over. Morgan is determined to capture Rick and take him away by the 9.00 train; but he is trapped in the town alone, with Belden and all his men now looking to kill him.

Ellen Wheeler, a rich widow, is recovering from a nervous breakdown. One day, while staring out the window, she witnesses a murder. But does anybody believe her?

During WW2 a British aircraft is shot down and crashes in Nazi held territory. The Germans capture the only survivor, an American General, and take him to the nearest SS headquarters. Unknown to the Germans the General has full knowledge of the D-Day operation. The British decide that the General must not be allowed to divulge any details of the Normandy landing at all cost and order Major John Smith to lead a crack commando team to rescue him. Amongst the team is an American Ranger, Lieutenant Schaffer, who is puzzled by his inclusion in an all British operation. When one of the team dies after the parachute drop, Schaffer suspects that Smith's mission has a much more secret objective.
