Silent Witness

Even gangland's cleverest "mouthpiece" meets his Waterloo with the D.A.'s blonde bombshell!

District Attorney Holden and his special investigator Betty Higgins are trying to convict brothers Joe and Lou Manson, silk-racket hoods, after they are indicted for murder. Their attorney, Bruce Strong, gets them off when the testimony given by Mrs. Roos proves to be perjured. Carlos, one of the Manson gang members, rightfully thinks he is not getting his rightful cut, and when he says this to the Mansons, they shoot him. He hangs on long enough to crawl to Holden's office. The Mansons call Bruce and tell him that one of their gang has squealed and that they are going after the District Attorney. Bruce tries to track down the D.A. and warn him, and follows him in his car as the D.A. goes out looking for the Mansons. The D.A. is killed when the Mansons run his car off the road, but his dog Ace bites Lou and is shot during this mêlée. Some rancher's children find the wounded Ace and take him home with them. Bruce is near the scene at the time, and the Mansons plant the gun used to shoot Carlos in his car. Bruce is indicted and convicted of the murder. Betty is convinced he is innocent and sets out to proves his innocence.
