Pendulum (1969)

Synopsis
Police Captain Matthews (George Peppard) believes he has successfully pinned a murder and rape conviction on Paul Sanderson (Robert F. Lyons) only to have the sentence overturned by the United States Supreme Court. When his wife Adele (Jean Seberg) is found murdered, Matthews finds himself on the other side of the law. The disillusioned suspect finds that his police cronies and friends have turned their backs on him, particularly when Senator Cole (Paul McGrath) goes on a much-publicized tirade against crime. Woodrow Wilson King (Richard Kiley) is the civil libertarian who has doubts about Sanderson's insanity defense and uncovers information about his sadistic alcoholic mother who lead him to become a murderous misogynist. Matthews feels something is not quite right when his police colleagues are all too eager to pin the crime on him in this engaging murder mystery. ~ Dan Pavlides, All Movie Guide
