Captain Mary Jane O'Malley, a highly decorated Marine Corps officer and divorced mother of two, ends her ill-advised affair with a chauvinistic senior officer, Major Nelson Gray, after she discovers he is married. Gray begins a campaign of terror against his former lover, even taking her children out of school without her permission. When he breaks into her home and holds her at knifepoint, O'Malley shoots Gray. The local court rules the killing a justifiable homicide, but the military is a man's world, and O'Malley is brought up on charges of first degree murder by the Corps. Her only hope is her counsel, Captain Walker Randall, but first she'll have to convince Randall that she's innocent. Based on a true story.
